Correlation between CT Perfusion Parameters and Microvessel Density and Vascular Endothelial Growth Factor in Adrenal Tumors
We evaluated the correlation between computed tomography (CT) perfusion parameters and markers of angiogenesis in adrenal adenomas and non-adenomas to determine if perfusion CT can be used to distinguish between them. Thirty-four patients with pathologically-confirmed adrenal tumors (17 adenomas, 17 non-adenomas) received CT perfusion imaging before surgery. CT perfusion parameters (blood flow ...
متن کاملPerfusion CT in Colorectal Cancer: Comparison of Perfusion Parameters with Tumor Grade and Microvessel Density
OBJECTIVE The purpose of this study was to prospectively compare pre-operative computed tomography (CT) perfusion parameters with tumor grade from colorectal adenocarcinoma (CRC) and to correlate pre-operative CT perfusion parameters with microvessel density (MVD) to evaluate angiogenesis in CRC. MATERIALS AND METHODS Pre-operative perfusion CTs were performed with a 64-channel multidetector ...
متن کاملCorrelations between vascular invasion, neural structures invasion and microvessel density with clinicopathological parameters in gastric cancer
Aim: Our objective in conducting this study was to estimate the presence of lymphatic, blood vessel and neural invasion on Hematoxylin & Eosin (H&E) staining and also, the microvessel density detected by immunohistochemistry (MVD), in gastric adenocarcinoma, as well as their relationship with the clinical, pathological and biological characteristics of the tumors. Materials and Methods: To asse...
متن کاملThe Use of CT Perfusion to Determine Microvessel Density in Lung Cancer: Comparison with FDG-PET and Pathology.
OBJECTIVE To investigate the validity of CT perfusion in assessing angiogenic activity of lung cancer. METHODS Fifty-six patients with lung cancer scheduled for elective surgical resection received 16-slice helical CT perfusion imaging. Time-density curve (TDC), blood flow (BF), blood volume (BV), mean transmit time (MTT) and permeability surface area product (PS) were calculated. 18F-deoxygl...
متن کاملSolitary pulmonary nodules: dynamic enhanced multi-detector row CT study and comparison with vascular endothelial growth factor and microvessel density.
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...
