Gong H, Yu L, Leng S, Hsieh S, Fletcher J, McCollough C
Med Phys
. 2025 Feb;
PMID: 39945452
Background: Accurate low-dose CT simulation is required to efficiently assess reconstruction and dose reduction techniques. Projection domain noise insertion requires proprietary information from manufacturers. Analytic image domain noise insertion methods...

. 2025 Jan;
PMID: 39865183
Purpose: To compare same-day photon-counting detector CT (PCD-CT) to conventional energy-integrating detector CT (EID-CT) for detection of small renal stones (≤ 3 mm). Methods: Patients undergoing clinical dual-energy EID-CT for...

. 2025 Jan;
PMID: 39853252
Background: We previously identified circulating and MRI biomarkers associated with the surgical management of Crohn's disease (CD). Here we tested associations between these biomarkers and ileal resection inflammation and collagen...

Abdom Radiol (NY)
. 2024 Dec;
PMID: 39692760
Purpose: To evaluate correlation between terminal ileal (TI) stricture diagnosis at MR enterography (MRE) and ileocolonoscopy (IC) in patients with Crohn's disease (CD). Methods: One hundred and four patients with...

. 2024 Nov;
PMID: 39547980
Objective: Ultrasound microvessel imaging (UMI) may offer noninvasive, highly sensitive microvessel imaging for assessing Crohn's disease (CD). However, a quantification metric that demonstrates a strong correlation with pathological inflammation is...
