A MRI compatible transducer operating at 5 MHz was evaluated to explore the feasibility of creating deep lesions in heart at a depth of at least 15 mm and the size of thermal necrosis in heart tissue was estimated as a function of power and time.
The application of IVIM-DWI MRI (intravoxel incoherent motion diffusion-weighted imaging) MRI (magnetic resonance imaging) in the evaluation of abnormal enhancement of the margin of hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA).

RATIONALE AND OBJECTIVES
23Na‑MR imaging requires lengthy acquisition times, it remains difficult to implement routinely in clinical workflows and limits broader clinical application. This study aimed to determine whether a TR of 60 ms (TR60) could maintain brain tumor conspicuity while reducing acquisition time compar...
