PURPOSE To examine a new way of body diffusion weighted imaging (DWI) using the short TI inversion recovery-echo planar imaging (STIR-EPI) sequence and free breathing scanning (diffusion weighted whole body imaging with background body signal suppression; DWIBS) to obtain three-dimensional displays. MATERIALS AND METHODS 1) Apparent contrast-to-noise(More)
BACKGROUND A retrospective study was performed to determine the indications for positron emission tomography (PET) using [(18)F]fluorodeoxyglucose (FDG) in patients with esophageal cancer, including those with early cancer, and to investigate whether the tumor-to-normal ratio (T/N ratio) could be used as a substitute for the standardized uptake value (SUV).(More)
OBJECTIVE In order to determine the reliable predictors of response to radiotherapy for rectal cancer, we assessed apoptosis, p53 and p21 in biopsy specimens collected before treatment, and investigated the relationships to the histological effect of irradiation and the degree of tumor shrinkage. METHODS Ninety-three patients with advanced rectal(More)
BACKGROUND Hepatic intra-arterial infusion chemotherapy of 5-fluorouracil (5-FU) or fluorodeoxyuridine (FUDR) has been a treatment option for liver metastasis from colorectal cancer. However, an optimal administration schedule of 5-FU is still controversial. This study was conducted to evaluate a suitable schedule from the viewpoint of 5-FU metabolites and(More)
The present study aimed to compare the results of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) at a single institution in Japan. Of the 212 patients with stage I/II/III colorectal cancer who received a curative resection, 98 patients underwent HALS and 114 patients underwent CL. The clinical background and post-operative(More)
