We conclude that EVS is an unlikely cause of MS since it is not present in most patients early in the disease and rarely involves more than one extracranial vein. It is likely to be a late secondary phenomenon.

Continuous progress in surgical technique of adjustable gastric banding and the increasing experience of surgeons have decreased the rate of complications. However, because different complications may have the same clinical presentation but require different treatment, to give a definitive diagnosis, the radiologist must be aware of the surgical procedures and possible sequelae.

Contrary to common perception, the advent of third- and fourth-generation scanners has lead to a significant increase in radiation dose to the patient per computed tomography (CT) head scan. With that in mind, a pilot study was designed with the objective of assessing the effectiveness of a dental-style protective bib in reducing the dose to the radiosensitive organs of the neck and thorax. Radiation doses over the thyroid gland and breast were measured with thermoluminenscent dosemeters and an ionization chamber respectively in 110 patients undergoing routine head scans. Half the patients wore the protective bib and collar. With lead protection, the thyroid measurements were reduced by an average of 45 % and the breast measurements by an average of 76 %. Similar results were seen in phantom measurements.

A case of extrathoracic herniation of the lung is described together with the radiological findings in this condition including the role of computed tomography (CT) in its management. In addition a review of the literature is presented which outlines the incidence, classification and clinical features of lung herniae. Some reference is made to possible methods of treatment.
