Apparent Diffusion Coefficient as an Imaging Biomarker for Spinal Disease Activity in Axial Spondyloarthritis

Apparent diffusion coefficient by diffusion-weighted magnetic resonance imaging as a sole biomarker for staging and prognosis of gastric cancer

OBJECTIVE To investigate the role of apparent diffusion coefficient (ADC) from diffusion-weighted magnetic resonance imaging (DW-MRI) when applied to the 7th TNM classification in the staging and prognosis of gastric cancer (GC). METHODS Between October 2009 and May 2014, a total of 89 patients with non-metastatic, biopsy proven GC underwent 1.5T DW-MRI, and then treated with radical surgery....

A new phantom using polyethylene glycol as an apparent diffusion coefficient standard for MR imaging.

In recent years, magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) has seen wide clinical use, such as for early detection of cerebrovascular diseases and whole body screening for tumors. The apparent diffusion coefficient (ADC) standard phantom, which mimics the ADC values of several lesions in the body, is indispensable for the development of new pulse sequences for DWI, ...

CD74 antibodies a biomarker of axial spondyloarthritis

How to measure disease activity in axial spondyloarthritis?

PURPOSE OF REVIEW The evaluation of disease activity in axial spondyloarthritis (SpA) is complex and multifactorial. Moreover, patients and physicians have different perspectives of the disease and none of the current single-item or combined indexes adequately unifies both perspectives. Recent efforts have been made to improve disease activity measurement in axial SpA. RECENT FINDINGS The Ass...

rhabdomyosarcoma metastasis to the breast: appearance on diffusion-weighted imaging and apparent diffusion coefficient sequences

rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
