Whole-body magnetic resonance imaging provides accurate staging of diffuse large B-cell lymphoma, but is less preferred by patients.

Background: Whole-body magnetic resonance imaging (wbMRI) allows general assessment of systemic cancers including lymphomas without radiation burden.
Aim: To evaluate the diagnostic performance of wbMRI in the staging of diffuse large B-cell lymphoma (DLBCL), determine the value of individual MRI sequences, and assess patients' concerns with wbMRI.
Methods: In this single-center prospective study, adult patients newly diagnosed with systemic DLBCL underwent wbMRI on a 3T scanner [diffusion weighted images with background suppression (DWIBS), T2, short tau inversion recovery (STIR), contrast-enhanced T1] and fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) (reference standard).

Article Synopsis
- The study focused on improving breast cancer diagnosis using diffusion-weighted imaging with background suppression (DWIBS), which typically has lower signal-to-noise ratio (SNR) but high specificity.
- It compared the image quality and reliability of apparent diffusion coefficients (ADC) derived from two imaging techniques: conventional SENSE and a newer method called echo-planar imaging with C-SENSE (EPICS).
- Results indicated that EPICS provided better lesion conspicuity, lower noise ratings, and higher SNR and contrast-to-noise ratios compared to SENSE, with excellent agreement in ADC measurements between the two methods.

A diffusion-weighted whole body imaging with background body signal suppression (DWIBS) is usually imaged as a whole body with Transverse (Tra). However, Tra has a large number of stations and a larger number than Coronal (Cor), so the scan time is longer. There are also drawbacks, such as signal unevenness between series.

Introduction: Breast cancer is a common malignant tumor among women, and the effectiveness of diagnosing its metastasis and recurrence has been demonstrated using diffusion-weighted whole-body imaging with background body signal suppression (DWIBS). However, DWIBS causes distress to patients due to the unique circumstances of magnetic resonance imaging (MRI). This study aimed to investigate the various distress factors caused by DWIBS among women with breast cancer and assess the effectiveness of a new MRI system designed with an environment incorporating relaxing technology.

Background: Accurate identification of high-risk multiple myeloma (HRMM) is important for prognostication. The degree of diffuse infiltration patterns on magnetic resonance imaging (MRI) is associated with patient prognosis in multiple myeloma. However, objective indexes to determine the degree of diffuse infiltration patterns are unavailable.
