Evaluating renal function with intravoxel incoherent motion in a unilateral ureteral obstruction model [PDF]

Current Urology
Background:. Patients with renal injury are at increased risk of exacerbating kidney damage from contrast-enhanced radiological examinations. Therefore, a noninvasive and sustainable method for assessing renal function without contrast agents is ...

Accurate estimation of intravoxel incoherent motion parameters based on implicit neural representation. [PDF]

Med Phys
Abstract BackgroundIntravoxel incoherent motion (IVIM) diffusion‐weighted imaging has important value in treatment response monitoring. However, traditional voxel‐wise independent fitting methods are highly sensitive to noise and do not utilize spatial correlation, resulting in unstable parameter estimation. Although existing deep learning methods have
