e15140 Background: The most important clinical point for the colorectal cancer patients after surgery is to find out local recurrence and distant metastasis to liver or lungs in early state. Recently, DWIBS (diffusion weighted whole body imaging with background body signal suppression) scan, one of the diffusion weighted MRI imaging methods, was developed, and it has been become used for diagnosis of lung cancer and bladder cancer instead of PET scan. In this report, we examined whether it was more useful method for the diagnosis of recurrence or distant metastasis of the colorectal cancer after surgery than PET/CT scan or not. Methods: All the 12 primary colorectal carcinomas were resected at the surgical division, Kumamoto Central Hospital, Fukuoka Saisekai Ohmuta Hospital and Kurume University Medical Center from 2000 to 2008. (Table 1) After surgery, 14 recurrent regions (seven liver metastasis, two lung metastasis and five local recurrence) were diagnosed by CT and MRI scans. Then all the cases were performed by DWIBS scan. And also the seven out of 12 cases (three liver metastasis, two lung metastasis and four local recurrence) were performed by PET scan. Conditions set before DWIBS scan were six hours of fasting with no restriction on drinking water and normal oral administration of regularly used drugs. No bowel preparation was carried out in any of the patients. Informed consent was obtained from each patient before DWIBS scan. Results: All the 14 metastatic and recurrent regions (seven liver metastasis, two lung metastasis and five local recurrence ) of 12 recurrent patients were performed by DWIBS, MRI and CT scans. Within the seven out of 12 recurrent patients (three liver metastasis, two lung metastasis and five local recurrence), performed by PET scan, all the liver and lung metastatic regions were detected, on the other hand, three out of four local recurrent regions were diagnosed but the other one was not diagnosed by PET scan. Conclusions: DWIBS is not only useful diagnostic method for local recurrence of colorectal cancer after surgery, but also less invasive method than PET scan.

Objective: Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) is now recommended as a first-line staging modality in prostate cancer patients, and the widespread use of DWIBS may lead to an increased frequency of incidental findings. The aim of this study was to evaluate the prevalence and clinical significance of incidental findings on whole-body magnetic resonance imaging (WB-MRI) with DWIBS. Methods: Data from 124 patients with prostate cancer (age, 76.5 ± 5.6 years), who underwent 1.5 T WB-MRI with STIR, TSE-T2, TSE-T1, In/Out GRE, and DWIBS sequences, were retrospectively analyzed. Findings unrelated to prostate cancer were considered as incidental findings and categorized into two groups based on their clinical implications, as follow: imaging follow-up or additional examinations was required (significant incidental findings) and no need to additional work-up (non-significant incidental findings). A Chi-square test was performed to compare the differences in the prevalence of significant incidental findings based on age (≤75 and>75 years old). Results: A total of 334 incidental findings were found, with 8.1% (n = 27) as significant incidental findings. Significant incidental findings were more frequent in patients over 75 years old than those of 75 years old or younger (28.6% vs  11.1%, p = 0.018). Conclusion: Clinically significant incidental findings, which required imaging follow-up or additional examinations, were commonly observed in prostate cancer patients on WB-MRI/DWIBS. Advances in knowledge: Some incidental findings were clinically significant which may lead to changes in treatment strategy. Checking the entire organ carefully for abnormalities, and reporting any incidental findings detected are important.
