Minimally Invasive Porcine Model for Chronic Thromboembolic Pulmonary Hypertension

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT To elucidate the complex pathophysiology of chronic thromboembolic pulmonary hypertension (CTEPH), a disease associated with bilateral fibrotic obstructions of the pulmonary arteries (PA) and microvascular changes, research relies on animal models, which often depend on invasive techniques, including open surgery.

Real-time cine and myocardial perfusion with treadmill exercise stress cardiovascular magnetic resonance in patients referred for stress SPECT

Journal of Cardiovascular Magnetic Resonance, 2010
Background To date, stress cardiovascular magnetic resonance (CMR) has relied on pharmacologic agents, and therefore lacked the physiologic information available only with exercise stress.

Low-field cine magnetic resonance imaging in aortic valve disease

The British Journal of Radiology, 1989
Abstract Cine magnetic resonance imaging (MRI) holds considerable promise as a means of detecting abnormal blood flow patterns within the heart and great vessels. To date, the majority of techniques employed have required moderate to high field strengths.

Pre‐Imaging Clinical Factors Associated With Cardiac MR Image Quality Using Large Language Model‐Enabled Data Extraction

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 565-578, August 2026.
ABSTRACT Background Poor cardiac MR image quality can prompt repeat examinations and hinder clinical decision‐making. Purpose To evaluate whether pre‐imaging clinical information, extracted using a large language model (LLM), is independently associated with cardiac MR image quality. Study Type Retrospective.

Development of respiratory motion-resolved hepatobiliary phase cine-magnetic resonance imaging for stereotactic body radiotherapy in liver tumor

Scientific Reports
Cine-magnetic resonance imaging (MRI) has been used to track respiratory-induced motion of the liver and tumor and assist in the accurate delineation of tumor volume.

Application of phase-contrast cine magnetic resonance imaging in endoscopic aqueductoplasty

Experimental and Therapeutic Medicine, 2013
The aim of this study was to evaluate the application of phase-contrast cine magnetic resonance imaging (MRI) in endoscopic aqueductoplasty (EA) for patients with obstructive hydrocephalus. The clinical diagnosis of hydrocephalus caused by aqueduct obstruction in 23 patients was confirmed by phase-contrast cine MRI examination.

Free‐Breathing 3D Whole Heart and Aorta Cine MRI Without Contrast Agent—Comparison to Clinical Standard

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 524-535, August 2026.
ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.

Deep‐Learning‐Based Image Reconstruction to Improve End‐Diastolic and Systolic Cardiac T1 Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 892-907, August 2026.
ABSTRACT Purpose To develop an image reconstruction method that enables increased spatial resolution cardiac T1 mapping in both the end‐diastolic and systolic phase, that shows high T1 agreement with the clinical standard. The resolution gain is achieved by increasing the acceleration rate of MOLLI single‐shot images to R = 4, while maintaining a ...

Real‐time motion tracking of a gold implant in water by Cherenkov lights

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The intra‐fraction motion of tumors during radiation therapy can be monitored using imaging systems based on X‐ray imaging (e.g., kV/MV radiography or CBCT) or magnetic resonance imaging (MRI). However, these techniques have limitations, including additional ionizing radiation dose and the need for complex, expensive equipment ...

AI‐surrogate structure and dose correlation for left anterior descending artery in lung stereotactic body radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The left anterior descending (LAD) coronary artery is a critical organ‐at‐risk in thoracic radiotherapy. In thoracic stereotactic body radiation therapy (SBRT), sharp dose gradients and poor LAD contrast on 4DCT scans introduce uncertainty in LAD dose assessment.
