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 Atherosclerosis is an inflammatory reaction of the vessel wall. Emphysema may induce systemic inflammation, part of which may be the development or progression of atherosclerosis. So, the relationship between emphysema and atherosclerosis, whether both are due to the same causative agent and pathogenesis or emphysema led to atherosclerosis, is still not clearly understood. So, the aim of this work is to study the relationship between carotid atherosclerosis versus pulmonary emphysema extent and airflow obstruction. Results Cigarette smoking index was higher in patients than controls. According to FEV1%, patients were classified into: GOLD 1 (mild): FEV1 ≥ 80% predicted, GOLD 2 (moderate): 50% ≤ FEV1 < 80% predicted, GOLD 3 (severe):30% ≤ FEV1 < 50% predicted, and GOLD 4 (very severe): FEV1 < 30% predicted. There was a significant difference between the studied groups as regard to ABG parameters. Emphysema score showed a positive correlation with thrombus size, plaque size, and stenosis percent. Approximately 2/3 of patients had atherosclerotic changes and the other 1/3 had increased IMT. GOLD staging, also, correlated with thrombus size and stenosis percent. So, there was a strong positive correlation between both emphysema score and GOLD staging and carotid atherosclerosis. Conclusion The relationship between emphysema and atherosclerosis is suggested to be the chronic inflammatory reaction (against the same risk factor) based on the positive correlation between carotid atherosclerosis versus emphysema score and GOLD staging. The inherence of emphysema and atherosclerosis may be considered a syndrome. If so, targeting the same pathogenic mechanism will be valuable for their control.
