Purpose To propose a highly accelerated, high‐resolution dynamic contrast‐enhanced MRI (DCE‐MRI) technique called GRASP‐Pro (golden‐angle radial sparse parallel imaging with imProved performance) through joint sparsity and self‐calibrating subspace constraint automated selection of contrast phases. Methods reconstruction enforces combination an explicit low‐rank subspace‐constraint temporal constraint. The basis used to construct the is learned from intermediate step using low‐resolution...
Intravenous (IV) contrast medium is sometimes withheld due to risk of complication or lack availability in patients undergoing computed tomography (CT) for abdominal pain. The from withholding understudied.
Background: Pancreatic adenocarcinoma (PC) is a highly lethal malignancy with survival rate of only 12%. Surveillance recommended for high-risk individuals (HRIs), but it not widely adopted. To address this unmet clinical need and drive early diagnosis research, we established the Cancer Early Detection (PRECEDE) Consortium. Methods: PRECEDE multi-institutional international collaboration that has undertaken an observational prospective cohort study. Individuals (aged 18–90 years) are...
Background: A number of patients with periampullary carcinoma deemed resectable on preoperative CT have their curative-intent surgery aborted the basis intraoperative findings. Objective: This study sought to identify imaging and clinical factors associated Whipple procedures for adenocarcinoma. Methods: Ten U.S., Canadian, French institutions contributed data this retrospective case-control 360 adults (220 men, 140 women; mean age, 68.6 ± 8.4 [SD] years) adenocarcinoma who underwent between...
Purpose To develop and evaluate a novel dynamic contrast‐enhanced imaging technique called RACER‐GRASP (Respiratory‐weighted, Aortic Contrast Enhancement‐guided coil‐unstReaking Golden‐angle RAdial Sparse Parallel) MRI that extends GRASP to include automatic contrast bolus timing, respiratory motion compensation, coil‐weighted unstreaking for improved performance in liver MRI. Methods In RACER‐GRASP, aortic enhancement (ACE) guided k‐space sorting respiratory‐weighted sparse reconstruction...

Purpose Golden‐angle radial sparse parallel (GRASP) MRI reconstruction requires gridding and regridding to transform data between Cartesian k‐space. These operations are repeatedly performed in each iteration, which makes the computationally demanding. This work aimed accelerate GRASP using self‐calibrating GRAPPA operator (GROG) validate its performance clinical imaging. Methods GROG is an alternative approach based on imaging, k‐space acquired a non‐Cartesian grid shifted onto information...
Background Uterine fibroids are a common benign tumor and can be symptomatic, necessitating resection. Surgical myomectomy is an effective treatment option with risk of disseminating occult uterine leiomyosarcoma (LMS), creating need for presurgical screening protocol. Clinical collaboration contrast‐enhanced MRI including T 2 diffusion‐weighted imaging (DWI) utilized as exam. Purpose To review the accuracy feasibility interdisciplinary prospective pelvis DWI system LMS prior to fibroid...
The purpose of this study was to compare the reproducibility and diagnostic performance 2D 3D ROIs for prostate apparent diffusion coefficient (ADC) measurements.The included 56 patients with cancer undergoing 3-T MRI including DWI (b = 50 1000 s/mm2) before radical prostatectomy. Histologic findings from prostatectomy specimens were reviewed denote each patient's dominant tumor a benign region visually decreased ADC. Three readers independently measured ADCs both areas using an ROI placed...
