CT and endoscopic ultrasound in comparison to endoluminal MRI: preliminary results in staging gastric carcinoma.

Purpose: To prospectively compare diagnostic parameters of a newly developed endoluminal MRI (endo-MRI) concept with endoscopic ultrasound (EUS) and hydro-computer tomography (Hydro-CT) in T-staging of gastric carcinoma on one patient collective.

Material And Methods: 28 consecutive patients (11 females, 17 males, age range 46-87 years, median 67 years) referred for surgery due to a gastric malignancy were included. Preoperative staging by EUS was performed in 14 cases and by Hydro-CT in 14 cases within a time frame of 2 weeks.

Preoperative embolization of a tumor-bearing horseshoe kidney via both channels of a concomitant aortic dissection.

Renal cell carcinoma arising in a horseshoe kidney is a rare entity. Preoperative tumor embolization can be performed to prevent massive bleeding complications during organ-preserving surgery. We report the first case of a patient with a tumor-bearing horseshoe-kidney in whom the preoperative embolization, already complex because of the abnormal vascular supply, was additionally complicated by an aortic dissection.

New coil concept for endoluminal MR imaging: initial results in staging of gastric carcinoma in correlation with histopathology.

Our aim was to conduct a prospective study to evaluate staging accuracy of a new coil concept for endoluminal magnetic resonance imaging (MRI) on ex vivo gastric carcinomas. Twenty-eight consecutive patients referred to surgery with a clinically proven primary gastric malignancy were included. Surgical specimens were examined with a foldable and self-expanding loop coil (8-cm diameter) at 1.
