What is DWIBS, the latest whole-body screening for cancer?
DWIBS (Diffusion-weighted Whole body Imaging with Background body signal) is an imaging method developed by a Japanese doctor and originated in Japan. The high-performance MRI system and advanced imaging methods enable whole-body cancer screening without the use of X-rays.
PET-CT is often compared to DWIBS as a test for systemic cancer, because PET-CT involves the administration of a radioactive drug into the body, while DWIBS has the advantages of no radiation exposure and a relatively short examination time (30 minutes to 1 hour).
Accuracy equivalent to PET-CT
No drug administration (injection)
No radiation exposure
Relatively short inspection time of 30 minutes to 1 hour
No dietary restrictions prior to testing (depending on medical facility)
Tests are available for diabetes and poor renal function.
Can be repeated for a short period of time without risk of radiation exposure
Suitable for detection of urinary tract cancers (kidney, ureter, bladder), which PET-CT is not good at
