Dr. Yunus Salim CM, Dr. Muni Sankar Reddy M

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1307-1315

Background: The shoulder arthroscopy is the gold standard of reference in most of the shoulder pathologies including Rotator cuff tears. However, it is an invasive surgical procedure with associated risks of surgery and anaesthesia. The objective of the present study is to find out how accurately the rotator cuff pathologies can be diagnosed by these imaging tests.
Aims and Objectives: To compare the Ultrasonography, MRI findings with the Arthroscopic findings of Rotator cuff pathology of the shoulder.
Materials and Methods: All patients in whom the history and clinical examination is suggestive of Rotator cuff pathology were included in the study. Patients were evaluated using high resolution Ultrasound (HRUS) Philips HD-11, Germany and 1.5-Tesla MRI [1.5 Tesla, GE, Excite HD and USA]. Ultrasonographic and MRI examination is performed by a single radiologist experienced in musculoskeletal ultrasonography and MR Imaging. A Real time high resolution USG imaging and MRI of the shoulder was performed in a standardized fashion and subsequently with therapeutic or diagnostic arthroscopy on the symptomatic shoulder. Results were analyzed.
Results: Considering arthroscopy as the final gold standard of investigation, out of the 24 patients studied, five (20.8%) had rotator cuff tendinosis/tendinopathy, four (16.6%) had PT RCT, twelve (50%) had FT RCT while the remaining three (12.6%) had normal rotator cuff. The average delay between the MRI examination and arthroscopic surgery was 6 days (range 0-27 days) but in one case, it was as long as 117 days. A total of five (20.8%) patients were in the age group < 40 years while another five (20.8%) were between 40-50 years age group. A majority of eleven (45.8%) patients were between 50-60 years old while three (12.6%) were above 60 years.
Conclusion: It should be noted that following USG of the shoulder performed by a dedicated radiologist, MRI offers little additional value, with regard to the detection of rotator cuff tears.

“A COMPARATIVE STUDY OF THE DIAGNOSTIC ACCURACY OF 1.5 TESLA MRI WITH ARTHROSCOPY IN THE EVALUATION OF LIGAMENTOUS INJURIES OF THE KNEE”

Dr. Disha Shah, Dr. Amlendu Nagar, Dr. Sheetal Singh, Dr. Sonal Banzal .

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 451-464

Background: Ligamentous injuries to the ligaments and menisci of the knee can lead to significant morbidity and may precipitate osteoarthritis.Arthroscopic diagnosis though invasive is considered as the gold standard. Various imaging modalities like CT scan and MRI have alsobeen used in the diagnosis of these injuries and the quest for the best technique goes on.
Aim: The aim of this study is to assess the diagnostic accuracy of 1.5 T MRI in cases of ligamentous injuries of the knee joint and compare its efficacy with arthroscopy.
Materials & Methods: This is a comparative observational study which included 50 patientswho were clinically suspected to be having ligamentous injuries of the knee. MRI was done for all these patients and all of them laterunderwent arthroscopy in the Department of Orthopaedics-IMCHRC.Statistical analysis was done to derive the sensitivity, specificity, positive predictive value (PPV) and the negative predictive value (NPV) and for this the findings at arthroscopy were taken to be the true diagnosis.
Results: The patients were commonly in the age group of 21-30 years and males with RTA being the commonest mode of injury and duration of injury commonly between 6weeks to 6 months.ACL tear was the commonest injury found in 76% followed by PCL tear in 38% , MM tear in 36%, LM tear in 32%. Regarding the efficacy of 1.5T MRI for ACL tears the sensitivity was 94.6%, specificity 76.9%, PPV 92.1%, NPV 83.3% and accuracy 90%. For PCL it was 94.4%, 93.8%, 89.5%,96.8%,94% respectively. For MM it was 94.7%,100%,100%,96.9%,98% respectively and for LM 83.3%,96.9%.93.9%,91.2%,92% respectively.
Conclusion: MRI is of proven diagnostic value in the evaluation of internal ligamentous injuries of the knee joint. It has a fairly good PPV and its routine use in all clinically suspicious ligamentous injuries of the knee may be recommended. Further since MRI has a high NPV, a normal MRI scan may be used to exclude any pathology and thus avoid an expensive and invasive procedure like arthroscopy.

Manoj Kumar, Sagar Goel, Nikhil L Gore, Varun Gautam, Mohit Jindal

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 615-628

Background: There is a debate around the existence, anatomy, and role of the so called
―anterolateral ligament (ALL). This study was conducted with a primary aim of finding out
and comparing the prevalence of the presence of anterolateral ligament and it’s three portions
(femoral, meniscal and tibial) in knees with and without ACL tear.
Methodology: This is a cross sectional study conducted in which A total of 96 patients
undergoing MRI knee for clinically evident ACL injury or history of chronic knee pain were
included in the study. Out of 96 patients included in the study, 48 patients had ACL tear
(Group A) and 48 patients did not have an ACL tear (Group B). Demographic data and
clinical information were noted for all patients. Descriptive variables were expressed as mean
and standard deviation for quantitative variables and frequency and percentages for
qualitative variables. The data was analyzed using SPSS® version 21.0. Categorical variables
were analyzed using Chi square test and for normally distributed data - t test was used. p
value <0.05 was considered as statistically significant.
Results: ALL was visualized in 65% of the patients included in the study. Its femoral
component was visualized in 56%, tibial component in 63% and meniscal component in 57%
of the patients. The three components were viewed together in 30% of the patients. We found
a significant association between ACL tear and the presence of ALL (p <0.001), with ALL
visualized in around 81%of knees with an ACL tear and only 48% of knees without an ACL
tear. Meniscal tears were significantly associated with the presence of ALL as out of the 62
patients in which ALL was visualized, 24 had an associated medial meniscal tear, 7 had
lateral and 3 had tear in both the menisci.
Conclusion: Our study demonstrated radiological evidence of the existence of the ALL.
Furthermore, we found presence of ALL to be significantly associated with ACL injury and
meniscal tear. Age, gender, or affected side was not found to be associated with the presence
of ALL.

European Journal of Molecular & Clinical Medicine, 2021, Volume 8, Issue 3, Pages 2890-2899

Introduction: The rotator cuff disorders constitute the most common cause of shoulder
pathologies. Ultrasonography and MRI are widely used in evaluating various shoulder
pathologies. USG of shoulder is simple, cheap, fast and non-invasive imaging technology
for detection of rotator cuff and non- rotator cuff abnormalities. In this study we have
assessed the usefulness of USG in diagnosing the shoulder pathologies and have correlated
with the MRI.
Aim: Evaluation of a patient with shoulder pathology with ultrasonography as the initial
line of imaging technique as compared to MRI, assessing the accuracy of ultrasonography
in diagnosing shoulder joint pathologies, especially rotator cuff abnormalities, using MRI
as a reference standard and correlating findings wherever possible.
Materials and Methods: Hundred patients were studied prospectively over a period of two
years. Study subjects included both men and women in all age groups with suspected
shoulder pathology, suspected to have musculo-tendinous origin. All patients underwent
USG evaluation of the shoulder joint followed by MRI of the affected shoulder.
Results: USG showed a sensitivity of 85%, specificity of 100%, PPV of 100% and NPV of
97% in diagnosing full thickness tear of rotator cuff using MRI as reference. For partial
thickness tears, it showed a sensitivity of 71%, specificity of 69%, PPV of 82% and NPV of
54%. Overall accuracy of USG in detection of any tear of rotator cuff with MRI as
reference was 82%. The strength of agreement between USG and MRI for the diagnosis of
any tear of rotator cuff is considered to be ‘substantial’ in our study (Kappa=0.635).
Conclusion: USG showed comparable results to MRI in assessment of rotator cuff
abnormality and should be used as first line of investigation in patients presenting with
shoulder pathologies. It proved to have high sensitivity and specificity for full thickness
tears with relatively less sensitivity and specificity in detection of partial thickness tear.

Jawwad Sami Ur Rahman, Sathish Kumar Selvaperumal, Rajasvaran Logeswaran

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 11, Pages 9144-9155

In this paper, a proposed hybrid algorithm using K-means and Fuzzy logic for brain segmentation, is developed, simulated and evaluated. The system identifies the white matter, gray matter and Cerebrospinal Fluid (CSF). The proposed system was tested using Magnetic Resonance Imaging (MRI), and evaluated in terms of the misclassification rate and percentage of clustering. The misclassification rate was found to be lesser in the proposed system as compared to the existing systems using K-means and Fuzzy logic. Further, the percentage of clustering is improved by the proposed system as compared to the existing algorithms. This work paves the way for future development of Neuro Fuzzy K-means algorithm in order to reduce the misclassification rate further in clustering the white matter, gray matter and CSF.

Batil Alonazi

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 10, Pages 311-319

Background: Technologists are exposed to a strong magnetic field (1.5-3.0 Tesla), higher than the earth magnetic field (≈0.5mT). In addition to that, the exposure to the radiofrequency (RF) may create currents producing skin burns. This study's objective was to assess the magnetic resonance imaging (MRI) safety practices in specific departments in Saudi Arabia in the Riyadh region, evaluate the incidence of biological effects and health implications of the electromagnetic fields present during MR scans, and to detect the occupational hazards. Methods: A survey questionnaire was designed and used to stimulate the target population's views on aspects of MRI safety and detected risks. The survey's target population includes consultants, radiologists, technologists, patients, and others who underwent MRI procedures. Results: A total of 28 technologists were responded from the five hospitals. The study results showed that 50% of the technologist reported various levels of effects, including vertigo and lack of concentration. It is well documented that exposure to MRI requires special consideration due to high magnetic field exposure. Conclusions: This study's main findings are that radiology nurses and patients in MRI units are highly exposed to the magnetic field, especially before and after MRI examination. Any department did not report projectile hazards. Staff is exposed to various degrees of radiation risks. No incident or accident was reported in all investigated hospitals. The staff is well protected in light of the current practice.

Segmenting brain tumors is a major challenge in the production of scientific pictures. To order to maximize care outcomes and increasing the hospital success rate, early detection of brain tumors plays an important part. A challenging and time-consuming job is the manual segmentation of brain tumors from large quantities of MRI images produced in clinical routine. Automatic brain tumor segmentation is possible. This article aims to analyze strategies for the segmentation of brain tumors dependent on MRI. Automatic segmentation using deep learning approaches has recently been proven common because these approaches accomplish the latest findings much better than other methods would solve this issue. Deep learning approaches may also provide for effective analysis and unbiased interpretation of vast volumes of picture evidence dependent on MRI. There are many papers on MRI based brain tumor segmentation which focus on traditional methods. Different from others, we concentrate on the recent trend in the field of deep learning. Next, the brain tumors and techniques for segmenting the brain tumor are added. Then, the new architectures are explored with a emphasis on the current development in deep learning methods. Finally, an evaluation is introduced and further improvements are discussed to standardize brain tumor segmentation procedures dependent on MRI in the day-to-day clinical practice.
