Background: Wrist pain is a challenge, and imaging plays an important role in the evaluation of wrist pain.Purpose: Assessment of the role of ultrasonography (USG) versus magnetic resonance imaging (MRI) in the diagnosis and evaluation of wrist pain Results: Out of 50 patients, 35 males (70%) and 15 females (30%) (age range 12-62 years; mean = 31.7 years) were included in the study. The sensitivity, specificity, and accuracy of MRI and USG for tendinopathy were 95%, 100%, and 97.5% and 95%, 100%, and 97.5% respectively. The sensitivity, specificity, and accuracy of MRI and USG for TFCC tear were 75%, 100%, and 87.5% and 0%, 50%, and 50% respectively. The sensitivity, specificity, and accuracy of MRI and USG for simple ganglion were 100%, 100%, and 100% and 75%, 100%, and 87.5% respectively. The sensitivity, specificity, and accuracy of MRI and USG for solid mass were 100%, 100%, and 100% and 100%, 100%, and 100% respectively. The sensitivity, specificity, and accuracy of MRI and USG for foreign body were 50%, 100%, and 75% and 100%, 100%, and 100% respectively. The sensitivity, specificity, and accuracy of MRI and USG for carpal tunnel syndrome (CTS) were 77.8%, 100%, and 88.9% and 88.9%, 100%, and 94.4% respectively. Overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of USG Vs MRI were 79.2%, 96.1%, 95.0%, 83.3%, and 88.0% and 89.8%, 98.0%, 97.8%, 90.9%, and 94.0% respectively. Conclusion: USG is near equal to MRI in the assessment of tendon abnormalities and better than MRI in the diagnosis of CTS and foreign body, but MRI is better than USG in the assessment of TFCC and in the assessment of swelling (simple ganglion) and characterization of masses.

Background: Characterization of tendon pathologies of the hand and fingers remains problematic, despite advances in imaging. By using clinical history and imaging appearance, one can determine the diagnosis. Ultrasonography (USG) may be used as the first imaging modality when MRI unavailable or has a higher cost for patients. Purpose: Assessment of role of USG in evaluation of tendons abnormalities in hand and fingersResults: USG detected 20 of 20 cases (100%) of tenosynovitis, 8 of 10 cases (80%) of trigger finger, 10 of 12 cases (83.3%) of tendon tear, 3 of 3 cases (100%) of foreign body impaction, 12 of 12 cases (100%) of simple ganglion, and 3 of 3 cases (100%) of solid masses with sensitivity, specificity, and accuracy 93.8%, 97.8%, and 95.8%, respectively. Conclusion: USG is a powerful, easy, and inexpensive imaging tool that allows accurate assessment of the hand and finger's tendons abnormalities.

Background: Pneumonia is a common and serious infectious disease that can cause high mortality. Lung ultrasound (LUS) is increasingly utilized in emergency and critical settings. The role of LUS in evaluation of pneumonia is becoming more and more important.Objective: The current study was performed to compare the diagnostic accuracy of lung ultrasound against other modalities for evaluation and follow up of pneumonia in adult patients.Patients and Methods: One hundred and eight patients (70 males, 38 females) aged 57.33 ± 9.39 years admitted to the Chest Department with pneumonia from March to November 2019. After institute ethical committee clearance and written informed consent, each participant underwent chest X-ray (CXR), LUS and computed tomography (CT) within 6 hours from admission by 2 different radiologists being blind to the results of the other examination to minimize the bias. Follow up US was done after adequate medical treatment (7-14 days) to detect its ability for following the patients up.Results: A total of 108 patients who fulfilled the eligibility criteria were enrolled in this study LUS showed positive findings in 101 (93.5%) patients in the form of isoechoic area in 6 (5.5%) patients, dynamic air bronchogram alone in 25 (23.1%) patients and the last one was associated with all other sonographic signs of the studied patients. During follow up period, 55 (54.5%) of cases showed total resolution, while 33 cases (32.7%) showed regressive course of their sizes. Ten cases (9.9%) showed rather stationary course, while three cases (2.9%) showed progression course. The associated pleural effusion was resolved in 36 cases (90%) out of 40. Compared to CT, LUS showed a sensitivity and specificity of 93.33% and 94.74% for pneumonia detection respectively with 95.4% PPV, 92.4% NPV, and 93.91% accuracy. Conclusion:LUS considered being a good diagnostic and following up tool when pneumonia is suspected, its results were closer to CT with minimal cost.
