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.
Arterial spin labeling (ASL) is a noninvasive imaging technique that labels the proton spins in arterial blood and uses them as endogenous tracers. Brain perfusion imaging with ASL is becoming increasingly common in clinical practice, and clinical applications of ASL for intracranial magnetic resonance angiography (MRA) have also been demonstrated. Unlike computed tomography (CT) angiography and cerebral angiography, ASL-based MRA does not require contrast agents.

- Diffusion-weighted imaging (DWI) is a medical imaging technique that visualizes water molecule movement in tissues, providing insights into their health based on how diffusion is affected by tissue structures.
- DWI faces challenges in abdominal imaging due to issues like large volumes, motion during scans, and difficulty with fat suppression, which can degrade image quality.
- Recent advancements, including scan acceleration methods, techniques to handle respiratory motion, and enhanced fat suppression, aim to improve abdominal DWI quality, paving the way for future clinical applications and the integration of artificial intelligence.
Purpose: Accurate assessment of cerebral perfusion in moyamoya disease is necessary to determine the indication for treatment. We aimed to investigate the usefulness of dynamic PCASL using a variable TR scheme with optimized background suppression in the evaluation of cerebral perfusion in moyamoya disease.
Methods: We retrospectively analyzed the images of 24 patients (6 men and 18 women, mean age 31.
Background And Purpose: An accurate assessment of the hemodynamics of an intracranial dural AVF is necessary for treatment planning. We aimed to investigate the utility of 4D-MRA based on superselective pseudocontinuous arterial spin-labeling with CENTRA-keyhole and view-sharing (4D-S-PACK) for the vessel-selective visualization of intracranial dural AVFs.
Materials And Methods: We retrospectively analyzed the images of 21 patients (12 men and 9 women; mean age, 62.
