Carpal tunnel syndrome.

Ultrasound (US) of the carpal tunnel adds value to the usual electrophysiology diagnosis by confirming doubtful results or evaluating patients who do not improve after surgery. US sometimes provides the surgeon or the referring physician with important information about normal variants or common or even rare causes of the nerve compression. The size of the median nerve must be calculated in the short axis by measuring the nerve cross-sectional area where the nerve is the thickest, in most cases at the proximal entrance of the carpal tunnel. Because the threshold of the nerve size varies in the literature, it is best to consider the cross-sectional median nerve area <8 mm(2) to rule out and ≥12 mm(2) to rule in the diagnosis of carpal tunnel syndrome.

[Extra-cardiac findings on coronary computed Tomography scanning]. / Anomalies extra-cardiaques de découverte fortuite en coroscanner.

BACKGROUND: Multi-detector-row computed tomography (MDCT) has emerged as method for non-invasive imaging of the heart. AIM: To investigate the frequency of the non cardiac findings in cardiac imaging with MDCT. METHODS: A total of 191 patients underwent cardiac imaging with 64-slice MDCT over a period of 8 months. The detected abnormalities were classified in major (implying an immediate workup and treatment or at least a further investigation) and minor abnormalities. RESULTS: Extra cardiac abnormalities were detected on 69 examinations (36 %). Major abnormalities were found in 17 % of the patients, and the minor abnormalities in 25,6 %. The scan revealed 4 cases of lung carcinomas, all at a still surgical stage. CONCLUSION: There were a significant number of non cardiac findings in cardiac MDCT. To avoid missing clinically important findings, we should carefully evaluate all the organs included in the scan.
