- "In discriminating between T3 and T4 tumors, even if the fat plane intervening between the primary tumor and adjacent organ is effaced, invasion is not likely to be present if a distinct and smooth interface is maintained between them, whereas an indistinct or irregular interface probably suggests invasion."
Staging of T3 and T4 Gastric Carcinoma with Multiplanar CT: Added Value of Multiplanar Reformations for Prediction of Adjacent Organ Invasion Kim YH et al. Radiology 2009; 250:767-775 - "A combination of transverse CT and multiplanar reconstruction (MPR) is more accurate than transverse CT images alone in aiding prediction of tumor invasion of adjacent organs, particularly the transverse colon or mesocolon and pancreas, and , therefore in helping to identify patients with T4 gastric cancer."
Staging of T3 and T4 Gastric Carcinoma with Multiplanar CT: Added Value of Multiplanar Reformations for Prediction of Adjacent Organ Invasion Kim YH et al. Radiology 2009; 250:767-775 - MPR images are useful in identifying candidates for extended surgery and in planning appropriate surgical procedures."
Staging of T3 and T4 Gastric Carcinoma with Multiplanar CT: Added Value of Multiplanar Reformations for Prediction of Adjacent Organ Invasion Kim YH et al. Radiology 2009; 250:767-775 - "Adding MPR images to transverse CT images improves the capability for distinguishing T3 from T4 gastric cancer and prediction of adjacent organ invasion."
Staging of T3 and T4 Gastric Carcinoma with Multiplanar CT: Added Value of Multiplanar Reformations for Prediction of Adjacent Organ Invasion Kim YH et al. Radiology 2009; 250:767-775 - "CTC showed a high sensitivity for nonpolypoid stage Tis and T1 adenocarcinomas 10 mm or greater in width despite the limited sensitivity for nonpolypoid adenomatous lesions, when performed using cathartic preparation and fecal tagging."
