Computed tomographic scanning versus radioisotope imaging in adrenocortical diagnosis - CK, HW, et al. () Citation Context ...mass. Small aldosteronomas are not always readily visualized by CT. When larger than 0.8 cm, localizing accuracies range between 60% and 80%, depending upon the type...
Computed tomographic scanning in sarcoidosis. Sarcoidosis is a granulomatous disease of unknown etiology that involves the lungs or intrathoracic lymph nodes in more than 90% of patients. The clinical spectrum of sarcoidosis is protean, but pulmonary manifestations often dominate. C... LJ 3Rd 被引量...
Overall image quality was again reported to be significantly better with the MBIR algorithm than AISR or FBP algorithms in cardiac CT scanning [22]. Subjective noise in images reconstructed with MBIR was significantly lower than ASIR, which was in turn significantly lower than FBP [22]. Further...

X-ray dose from computed tomography (CT) scanners has become a significant public health concern. All CT scanners spray x-ray photons across a patient, including those using compressive sensing algorithms. New technologies make it possible to aim x-ray b
Location and extent of renal gas are best evaluated by computed tomographic scanning. Intraparenchymal gas usually requires nephrectomy, whereas successful therapy of gas limited to the collecting system involves medical management, with a ... G.V.,Evanoff,and,... - 《American Journal of Medicine...
Computed tomographic scanning is faster and less expensive, and involves lower radiation doses to the patient than scintigraphy. Adrenocortical isotope scanning as a routine procedure has been superseded by computed tomographic scanning at the Mayo Clinic. 展开 ...
CT scanning of the modern fruit specimen; top view (a) and side view (b), transverse sections in the endocarp (c,d) Ov ovules; longitudinal section (Se seed) (e), and the shape and form of the whole cone (f). Full size image Microchemical analysis of the archaeobotanical material ...
Computed tomographic radiomics exhibit a significant prognostic value in COVID-19 patients. First of all, the TSS score in the non-survivor group is significantly higher as compared to the discharged group and the group of patients hospitalized for longer than 3 weeks. Non-survivors had statistical...
The CT projections are then converted into tomographic 3D image slices taken through the subject in a process termed reconstruction. This mathematical process takes 2D image elements (pixels) from the projections and then “back-projects” them to form reconstructed 3D image elements (voxels) in ...
