Diffusion-weighted Whole body Imaging with background suppression is a background diffusion resonance imaging technique. The purpose of this technique is to assess the lesions of the whole body in the early detection of cancer, lymph nodes, analysis as well as monitoring of malignant lesions.

1. What does DWIBS mean?

Background diffusion resonance imaging (DWIBS) is an improved technique of diffusion resonance imaging (DWI) first introduced in 2004, currently being developed and applied in Vietnam.

In diffusion resonance (DWI), tissue regions with water molecules that are restricted from diffusion will increase signals on DWI, in contrast to those where water molecules are not restricted from diffusion i.e. freely moving water molecules will decrease on DWI. DWIBS also enables signal enhancement in lesions with limited diffusion such as monolithic tumors – thrombosis and lymph nodes, while it suppresses the signals of the body's normal tissues, blood, muscles and fat. The aim is to increase the contrast of lesions.

DWIBS enables early detection and diagnosis of cancer

Patients in this case can breathe normally, which is an advantage over the pulse sequences of the resymable imaging technique. The DWIBS technique allows thin layers to be cut, which in turn allows us to reproduce MPR and MIP hosy-dimensional images, so will give the image the same as the PET-CT snapshot.

Currently, DWIBS imaging is a method that can be used to replace PET-CT scans (which use radioactive and X-ray drugs), patients will not be affected by radioactive and radioactive substances, so the DWIBS method is the preferred method for early diagnosis of oncological cancers. , thrombophly, lymph nodes and monitor the progress of tumors.

In addition to the advantages of DWIBS in early diagnosis of cancer, DWIBS also makes sense in the diagnosis of anesthies and other pathology lesions of the bodies in the body.

2. How is the DWIBS shooting method performed?

  • Place the sick person in a strong from 1.5 – 3.0 Tesla (T).
  • Broadcast the radio on the sick.
  • During the scan, the technicians will use the different parameters or the available parameters of the DWIBS scan that apply to the patient.
  • Build images with recorded signals: people convert the captured signals into those in space and are recorded by the computer, after which the computer will rebuild the images of the cross-section based on the recorded parameters.

3. Who can't take DWIBS?

All patients with contrainatrained with a resymable scan cannot have a full-body diffusion resonance imaging scan that erases the background:

  • Patients carrying items containing from the patient: Patients carrying pacemakers, surgical clips, artificial heart valves, shrapnel in the danger zone, transplants in cochlear implants, cathinal brain valves, newly placed dynamic stents (less than 2 weeks)… Patients carry other properties such as end medulla nails, artificial hip joints, metal screw braces …
  • Relative contraincularity: agitated patients, fear syndrome located in a closed cage.
