In both Japanese and English, we will introduce MRI examinations, which are useful for detecting malignant tumors throughout the body!
The future is at hand: MRI examinations throughout the body
For researchers in the world
Compared to conventional CT, MRI allows for qualitative analysis of benign or malignant disease, not just morphology. Compared to PET/CT, MRI enables early assessment of therapeutic effects, is inexpensive, and does not require radioactive isotopes.
Diffusion-weighted MRI is useful for differentiating between benign and malignant pulmonary masses, diagnosing the N factor, M factor, and stage of lung cancer, evaluating vascular, and mediastinal invasion, and determining the effectiveness of chemotherapy and radiotherapy for lung cancer. MRI is also useful for evaluating whether mediastinal lesions or pleural lesions are malignant or benign. Furthermore, diffusion-weighted MRI images are not only useful for the early diagnosis of cerebral infarction, but are also useful in diagnosing malignant tumors in the chest, abdomen, breast, colon, gynecological, and urological areas, and can also diagnose distant metastases, including bone metastases.
DWIBS (Diffusion-weighted whole-body imaging with background suppression), an MRI test that searches for cancer lesions throughout the body in a single test, can detect malignant lesions in the same way as PET-CT, and malignant lesions are easy to recognize because they glow white.
We believe it is also useful for health checkups for residents who are allergic to radiation exposure. In short, DWIBS can be said to be an inexpensive PET-CT without radiation exposure. PET-CT and DWIBS have almost the same results, and in some cases DWIBS outperforms PET-CT, and in other cases PET-CT outperforms DWIBS.
I would be happy if this blog could be of some use to readers, and they continue to make progress in MRI research.

In the MRI diffusion-weighted image, the lung cancer can be identified as glowing.
