PET/CT scanners offer a hardware solution for aligning and viewing functional and anatomic images that is immune to many of the errors in strictly software registration techniques. Moreover, PET attenuation-corrected emission scans benefit from the use of the onboard CT for fast, low-noise attenuation correction. Along with the significant improved localization and reduced acquisition time, PET...

In the paper some results of the modelling of the clinical trial (CT) process are presented. CT research is a complex process which includes the protocol editing, its use and implementation in the CT experimentation, and the evaluation of the results. To improve the medical research, it is necessary to consider the CT research process as a whole. We structured the CT research process in three s...

18-Fluorodeoxyglucose (FDG-PET/CT) is an established imaging modality that has been proven to be of benefit in the management of aggressive B-cell non-Hodgkin's lymphoma, such as diffuse large B-cell lymphoma and advanced stage follicular lymphoma. The combination of anatomic and functional imaging afforded by FDG-PET/CT has led to superior sensitivity and specificity in the primary staging, re...

Incidental indeterminate solitary pulmonary nodules (SPN) that measure less than 3 cm in size are an increasingly common finding on computed tomography (CT) worldwide. Once identified there are a number of imaging strategies that can be performed to help with nodule characterization. These include interval CT, dynamic contrast enhanced computed tomography (DCE-CT), (18)F-fluorodeoxyglucose posi...

Expiratory CT scan is usually obtained as supplement to normal inspiratory CT scan to recognize air-trapping, which is expression of small airways obstruction. In some patients the air-trapping may be the only sign of an early-stage small airways disease in an otherwise normal lung.The purpose of this article is to illustrate pathologic conditions, namely obliterative bronchiolitis, in which ex...

Chromosome territories (CTs) in higher eukaryotes occupy tissue-specific non-random three-dimensional positions in the interphase nucleus. To understand the mechanisms underlying CT organization, we mapped CT position and transcriptional changes in undifferentiated embryonic stem (ES) cells, during early onset of mouse ES cell differentiation and in terminally differentiated NIH3T3 cells. We fo...

BACKGROUND Primary intracerebral hemorrhage (PICH) remains the deadliest and most disabling form of stroke. The aim of our study was to determine the potential predictors for survival and neurological recovery in PICH patients by clinical-computed tomographic (CT) correlation. MATERIALS AND METHODS A prospective study conducted among PICH patients at a tertiary care hospital. The clinical and...

The reported sequences of the human and mouse Na+-driven Cl-/HCO3(-) exchangers (NDCBEs) differ greatly in their extreme cytosolic COOH termini (Ct). In human NDCBE (NDCBE-B), a 17-amino acid (aa) sequence replaces 66 aa at the equivalent position in mouse NDCBE (NDCBE-A). We performed 5'- and 3'-rapid amplification of cDNA ends (RACE) on human brain cDNA, followed by PCR of full-length cDNAs t...
