RESUMO
Background: Knee is one of the major joints involved in kinesis. With increasing involvement in sports related activities especially in young people, Trauma related knee pathologies have increased. An accurate diagnosis regarding the type and extent of injuries is essential for early operative as well as non-operative treatment. Methods:This prospective study included total of 82 cases. The patients were referred to the department of Radiodiagnosis from indoor and outdoor departments of Guru Nanak Dev Hospital, Amritsar with suspicion of internal derangement of the knee and with history of knee trauma.Results:The most common age group involved was young males between 15-34 years. In all age groups most of the patients were males. Most common ligament to be injured was Anterior Cruciate Ligament (ACL). Partial tears were more common than complete tears. Posterior Cruciate Ligament (PCL) tears were less common. Medial Collateral Ligament (MCL) tears outnumbered Lateral Collateral Ligament (LCL) tears and grade 2 tears were more common in both. Among the meniscal injuries Medial Meniscus (MM) tears were more common than LM and grade 3 signal was more common in both. Most of the patellar retinaculum injuries were associated with Anterior Cruciate Ligament ACL tears.Conclusions:Post-traumatic pre-arthroscopic MR imaging evaluation has proved to be cost-effective. MRI is an accurate imaging modality complementing the clinical evaluation and providing a global intra-articular and extra-articular assessment of the knee.
RESUMO
Detecting and characterization of hepatobiliary masses is one of the most confusing and controversial challenges in imaging today. Aims and objectives: To evaluate the role of Ultrasound and Computed Tomography in hepatobiliary masses and know the exact site of origin of lesion and its extension into surrounding structures. Methods: In this study, 100 cases of hepatobiliary masses were subjected to with USG and CECT abdomen. Imaging findings were evaluated and tabulated and correlated with the histopathological findings, surgical findings and follow up. The findings were checked and statistically tabulated. Results: Out of a total 100 patients included for study, most patients were in age range of 51 – 60 years. Males : Females ratio was 55 : 45. Out of 100 cases 73% were hepatic masses, 18% gall bladder masses and 8% common bile duct masses. 51 being true benign and 49 lesions being true malignant. Sensitivity (%) and Specificity (%) of diagnosing these lesions on USG was 84.5% and on 86.6% respectively. Sensitivity (%) and Specificity (%) of diagnosing these lesions on CT was 92.2% and on 94.8% respectively. Conclusion: Hepatobiliary masses remain a diagnostic challenge. These lesions are frequently caused by benign, malignant and metastatic etiologies. We conclude that USG plays an important role as an initial screening modality and as an adjunct to CECT and Triphasic CT in the evaluation of hepatobiliary masses.
