Positron Emission Tomography/Computerized Tomography (PET/CT) is an important assessment method in restaging of oncology patients. Its ability to detect the metabolic/functional changes in patients with colorectal cancer during the early stages, in which morphological changes cannot be documented, is significantly superior to other imaging modalities.
The accurate targeting of tumours with maximal sparing of normal tissues has been the foremost goal of radiotherapy practice. Over the past two decades, the ability to achieve this goal has improved greatly through advances in imaging technology, specifically the development of computerized tomography (CT), magnetic resonance imaging (MRI), positron-emission tomography (PET) and fusion PET/CT [...
BACKGROUND AND PURPOSE The spot sign score (SSS) provides risk stratification for hematoma expansion in acute intracerebral hemorrhage; however, external validation is needed. We sought to validate the SSS and assess prognostic performance of individual spot characteristics associated with hematoma expansion from a prospective multicenter intracerebral hemorrhage study. METHODS Two hundred tw...
Granular cell tumors are rare soft tissue neoplasms, among which only 2% are malignant, arising from nervous tissue. Here we present a case of a large esophageal granular cell tumor with benign histopathological features which metastasized to the liver, but showing on positron emission tomography-computerized tomography standardized uptake value suggestive of a benign lesion.

We assessed Calcofluor white staining, Aspergillus polymerase chain reaction, and a galactomannan enzyme immunoassay for diagnosis of fungal infection with use of computed tomography-guided percutaneous lung biopsy specimens obtained from 61 patients. The sensitivity and specificity of computerized tomography, Aspergillus polymerase chain reaction, and galactomannan enzyme immunoassay were 100%...
A 59 year old woman was admitted to hospital in January 1989. She had difficulty in walking and urinary incontinence for three months. Examination disclosed spastic paraparesis and gait ataxia. No demential sign was found. Computerized tomography showed ventricular dilatation. The symptoms and signs. computed tomography (CT)findings and other investigations confirmed the diagnosis of normal pre...
