Magnetic Resonance Imaging

5.2K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Faster prostate cancer MRI scans are achievable by reducing sequence times while maintaining diagnostic quality. Techniques like undersampling and AI reconstruction show promise for quicker multiparametric MRI (mpMRI) acquisition.

Area of Science:

  • Radiology and Medical Imaging
  • Artificial Intelligence in Healthcare
  • Oncology Imaging

Background:

  • Rising global prostate cancer incidence necessitates efficient diagnostic tools.
  • Multiparametric MRI (mpMRI) is crucial for prostate cancer diagnosis, but lengthy scan times strain healthcare resources.
  • Reducing mpMRI scan duration is essential for improving patient throughput and accessibility.

Purpose of the Study:

  • To review and analyze recent techniques for accelerating prostate cancer mpMRI acquisition.
  • To evaluate methods for shortening T2W and DWI sequences while adhering to PI-RADS guidelines.
  • To discuss the implementation, benefits, drawbacks, and diagnostic performance of faster mpMRI techniques.

Main Methods:

  • Review of novel acquisition techniques focusing on efficient data sampling (fewer averages, b-values).
