PURPOSE To prospectively compare pulmonary function tests and helical computed tomographic (CT) indexes for quantifying pulmonary emphysema with macroscopic and microscopic morphometry. MATERIALS AND METHODS The investigation was approved by the local ethics committee, and written informed consent was obtained from patients. Multi-detector row CT of the thorax was performed with simultaneous ...

PURPOSE To evaluate enhancement dynamics of solitary pulmonary nodules at multi-detector row computed tomography (CT) and to correlate results with extent of tumor angiogenesis in pathologic specimens. MATERIALS AND METHODS One hundred thirty-one patients with solitary pulmonary nodules underwent unenhanced thin-section CT, followed by dynamic helical CT (throughout the nodule for 30 mm along...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-208578 DESCRIPTION A well-built 31-year-old man presented with deformity and restricted movements of the left wrist joint. He gave a history of injury due to a fall 8 months earlier, for which he was initially treated with a wrist slab for 3 months. Clinical examina...

PURPOSE To evaluate several protocols for depiction of the urinary collecting system with multi-detector row computed tomographic (CT) urography. MATERIALS AND METHODS Fifty-one patients with hematuria or a suspicious renal mass underwent CT urography, during which thinly collimated (1-mm) pyelographic phase scanning was performed 8-10 minutes after contrast medium administration. Patients we...

PURPOSE To determine the diagnostic capability of low-dose CT (50 mAs) in comparison to standard-dose CT (150 mAs). MATERIALS AND METHODS Fifty-nine consecutive patients underwent two non-contrast chest CT scans with different current-time products (50 and 150 mAs at 120 kVp) on a 64-detector row CT scanner. Three board certified chest radiologists independently reviewed 118 series of 2 mm-th...

BACKGROUND The optimal placement of suture anchors in transosseous-equivalent (TOE) double-row rotator cuff repair remains controversial. PURPOSE A 3-dimensional (3D) high-resolution micro-computed tomography (micro-CT) histomorphometric analysis of cadaveric proximal humeral greater tuberosities (GTs) was performed to guide optimal positioning of lateral row anchors in posterior-superior (in...

in in order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (rcbd) with 4 replications in saat-loui agricultural station of west azerbaijan province. in this research, the first factor (a) contained two levels 20 and 40 cm inte...
