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.

To assess role of MRI in detecting female infertility.
Materials & Methods:Eighty- six women age ranged 20- 40 years were included in the
study. All underwent MRI using 1.5 Tesla unit equipped with a 32 phased-array surface
coil. Causes of female infertility was recorded.
Results: Age group 20-30 years comprised of 50 and 31-40 years had 36 patients. Various
causes of female infertility was PCOS in 12, tubal disease in 18, pelvic inflammatory
disease in 10, endometriosis in 8, leiomyoma in 6, adenomyosis in 12 and endometrial
polyps in 20 cases. A significant difference was observed (P< 0.05).
Conclusion: MRI is an excellent non-invasive, radiation-free modality for the evaluation
of female infertility; its superior soft-tissue contrast resolution and multiplanar evaluation
generate exquisite anatomical details.

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.

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.

Abstract: Background: Understanding the RELATION between anterior cruciate ligament
and postero lateral corner TRAUMA with antero-lateral ligament of knee with it’s clinical
diagnosis would help us better understand the pattern of injury and to take proper
treatment action .Objectives :To find the correlation between pattern of injury of
anterolateralligament , anterior cruciate ligament and posterolateral corner injury on MRI
with it’s clinical correlation and associated findings. Methodology: A cross-sectional study
will be done at Acharya Vinoba Bhave Rural Hospital, Sawangi, involving52 patients who
present with knee trauma for MRI. The sample will be selected and involvement of
Anterior cruciate ligament ,postero lateral corner injury and antero-lateral ligament with
associated findings will be evaluated using T1, T2 and PD MRI sequences. These will be
compared and there association will be calculated which can be used for better planning of
treatment. Results: After appropriate statistical analysis, we expect to find association
between anterolateral ligament and anterior cruciate ligament tear with posterolateral
corner injury and this will be considered for reconstruction. Conclusion: In this
observational study, we expect associations between injured ligaments with aid of clinical
findings . We also expect to find a positive association between anterolateral ligament with
posterolateral corner injury and anterior cruciate ligament tear.
