Investigating Associations Between Signal Intensity of Silent MR Angiography and Hemodynamic Information From 4D Flow MRI in Brain Arteriovenous Malformation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. Objectives To evaluate the relationship between Silent MRA SI and 4D flow‐derived hemodynamic parameters and examine whether Silent MRA‐based metrics are associated with symptomatic hemorrhage in BAVM.

Capillary malformation-arteriovenous malformation syndrome: a multicentre study

, 2021
Capillary malformation-arteriovenous malformation (CM-AVM) syndrome is a rare syndrome with characteristic skin lesions that are associated with fast-flow vascular malformations (FFVMs) in one-third of patients.

Radiation‐Induced Cutaneous Tissue Reactions in Neurointerventional Procedures: A Systematic Review of Reported Effects and Associated Dose Levels

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Neurointerventional procedures can deliver high localised skin doses and may cause radiation‐induced cutaneous tissue reactions, yet the doses at which these occur have not been synthesised specifically for this setting. We systematically reviewed reported cutaneous reactions and associated radiation doses after fluoroscopy‐ or digital ...

A Case of Coexistence of an Arteriovenous Malformation and Hemangioma of the Maxillary Sinus

Arteriovenous malformation or arteriovenous hemangioma of the maxillary sinus is relatively rare. The coexistence of the 2 lesions in the maxillary sinus is extremely rare. Such lesions may cause severe epistaxis due to arterial bleeding.

Color Doppler sonography of uterine arteriovenous malformation.

, 2000
Arteriovenous malformation of the uterus is a rare but potentially life-threatening lesion. We report a case of arteriovenous malformation of the uterus in a 19-year-old nulliparous woman.

Fat‐Containing Soft Tissue Lesions of the Limbs and Body Wall—A Pictorial Essay

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Lipomatous tumours are frequently encountered on imaging. The spectrum of lipomatous tumours ranges from simple lipomas, which can be monitored clinically, to high‐grade liposarcomas, which require timely, multidisciplinary management. The presence of fat within lesions may also be observed in non‐lipomatous tumours, as well as in a variety of

Prenatal imaging phenotypes and outcomes of umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies: A historical cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This retrospective cohort compared umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies. Type III was the most common subtype in singletons, whereas Type II was the most common in twins. Fetal growth restriction was more frequent in twins, but primary structural anomaly rates were similar.
