Water enema computed tomography (WE-CT) in the local staging of low colorectal ...
Caseiro-Alves, F; Gonçalo, Manuela; Ilharco, J; Agostinho, A; Castro e Sousa, F; Vilaça-Ramos, HBACKGROUND: To determine the accuracy of computed tomography performed with a water enema application (WE-CT) in the local staging of low colorectal neoplasms and to compare the results with those of transrectal ultrasonography (TRUS). METHODS: Forty patients with low colorectal tumors were evaluated prospectively by CT with the simultaneous administration of a lukewarm rectal enema (0.5-1.5 L). Thin slices (5 ...
Induced pneumoperitoneum in CT evaluation of peritoneal carcinomatosis
Caseiro-Alves, F; Gonçalo, Manuela; Abraúl, E; Pinto, E; Oliveira, CF; Vilaça-Ramos, HBACKGROUND: Imaging of peritoneal carcinomatosis is a well-known problem even for technologies as recent as computed tomography (CT). The purpose of this study was to evaluate whether CT performed after induced pneumoperitoneum (CT-PP) could have a higher sensitivity in the detection of peritoneal implants over conventional CT. METHODS: Five patients with known ovarian malignancies underwent standard CT and CT-...
