Purpose: The aim of this study was to compare the accuracy of colonoscopy (CS) and CT colonography (CTC) in the measurement of colorectal polyps using pathological size as a reference.
Materials And Methods: The analysis included 61 colorectal polyps in 28 patients who underwent preoperative CTC at our institution. All polyps were endoscopically resected.
Purpose: Wall-carving technique (WC) is a special volume rendering technique of three-dimensional CT gastrography that can illustrate the enhancement of gastric wall at an arbitrary depth. We conducted the present study to evaluate the impact of contrast enhancement based on layer depth on WC of gastric cancer and to correlate them with pathological findings.
Methods: The subjects of this retrospective study consisted of 36 patients with advanced gastric cancer (22 men, 14 women; age range, 39-90 years; median, 67 years) who underwent contrast-enhanced CT before surgery.
Objective: The purpose of this study was to examine the relationship between the CT features of the primary-site gastric cancer and the concurrent existence or postoperative recurrence of hepatic metastasis.
Materials And Methods: From January 2013 to July 2016, 125 patients with advanced gastric cancer who were evaluated by gastroscopy and contrast-enhanced CT at our institution were included. Eleven patients had hepatic metastasis at the time of diagnosis (synchronous hepatic metastasis).
Purpose: To evaluate the diagnostic value of contrast-enhanced computed tomography gastrography (CE-CTG) to predict the histological type of gastric cancer.
Materials And Methods: We analyzed 47 consecutive patients with resectable advanced gastric cancer preoperatively evaluated by multiphasic dynamic contrast-enhanced CT. Two radiologists independently reviewed the CT images and they determined the peak enhancement phase, and then measured the CT attenuation value of the gastric lesion for each phase.
Purpose: To evaluate the enhancement pattern of diffuse-type gastric cancers (DGCs) on multiphasic contrast-enhanced computed tomography gastrography (CECTG).
Methods And Materials: We studied 21 consecutive clinically diagnosed DGC patients who underwent CECTG. Gastric distension was obtained using effervescent granules.
