Background: The use of combined positron emission tomography/computerised tomography (PET/CT) scanners in oncology has been shown to improve the staging of tumours and the detection of relapses. However, mis-registration errors are increasingly recognised to be a common pitfall of PET/CT studies. Case Presentation: We report a patient with a germ cell tumour of the testis, who underwent a PET/C...

Thirty-six patients with angiographically confirmed intracranial arteriovenous malformations have had computerised tomographic scans performed as part of their investigation. This study demonstrates the incidence of haematoma formation after haemorrhage, the frequency of calcification not visible on plain radiographs, and describes the possible causes for a complicating hydrocephalus. Further i...

Among the echocardiograms of 844 patients of the International Goodwill Hospital from January 1980 to April 1981, 700 showed clinically inexplicable extra echo spaces. Fifty of the 700 had computerised tomography of their hearts which showed the extra echo spaces to be caused either by anterior or posterior subepicardial fat. Six of the 50 cases had both fat and pericardial effusions, which are...

Sixty-six elderly subjects (mean age 77 years) whose mental state was assessed clinically and by simple psychometric tests have been studied by computerised tomography. The mean maximum ventricular area in the 17 mentally normal subjects was above the upper limit of normal for younger subjects, and there was a broad relationship between increasing ventricular dilatation and increasing intellect...

The aim was to reconsider the "Guidelines for initial management of head injury in adults"--particularly with respect to the indications for computerised tomographic (CT) scanning--suggested by "a group of neurosurgeons" over a decade ago and still followed in some accident and emergency (A&E) departments. These recommendations are placed in the context of more recent research and the increased...
