Influence of self-reported vascular health and physical activity level on intravoxel incoherent motion imaging response to exercise in chronic low back pain

Frontiers in Physiology
IntroductionIn individuals with chronic low back pain (CLBP), degenerative changes in paraspinal muscles, such as fatty infiltration and reduced vascularization, may impair muscles’ physiological response to exercise, limiting recovery potential ...

Non-invasive identification of KRAS mutation in rectal cancer using hybrid intravoxel incoherent motion and diffusion kurtosis model

World Journal of Surgical Oncology
Background and purpose Sarcoma Viral Oncogene Homologue (KRAS) mutation status is a crucial biomarker in rectal cancer as KRAS mutations confer resistance to anti-EGFR targeted therapies and influence chemotherapy selection, affecting treatment decisions

Potential predictive value of IVIM MR for xerostomia in nasopharyngeal carcinoma

Radiotherapy and Oncology
Xerostomia, caused by radiation-induced parotid damage, is the most commonly reported radiotherapy (RT) complication for nasopharyngeal carcinoma (NPC). The purpose of this study was to evaluate the value of intravoxel incoherent motion (IVIM) MR in monitoring radiation-induced parotid gland damage and predicting the risk of xerostomia.Fifty-four NPC ...

A Method for Imaging the Ischemic Penumbra with MRI using IVIM

Background and purpose: In acute ischemic stroke, the amount of "local" CBF distal to the occlusion, i.e. all blood flow within a region whether supplied antegrade or delayed and dispersed through the collateral network, may contain valuable information ...
