Fast Spiral Coronary Artery Imaging

Magnetic Resonance in Medicine, 1992
AbstractA flow‐independent method for imaging the coronary arteries within a breath‐hold on a standard whole‐body MR imager was developed. The technique is based on interleaved spiral k‐space scanning and forms a cardiac‐gated image in 20 heartbeats. The spiral readouts have good flow properties and generate minimal flow artifacts.

Spiral CT arterial portography of the liver.

Radiology, 1993
The enhancement characteristics of the liver, aorta, and hepatic vein were evaluated during computed tomography with arterial portography (CTAP) performed with spiral technique in 10 patients. The attenuation of the liver was nearly constant over the scanning interval (average attenuation, 168 HU +/- 16).

A spiral artery in the ovary of the rabbit

American Journal of Obstetrics and Gynecology, 1947
Abstract A spiral artery within the hilus of the ovary is demonstrated. It is formed by a helix-type of formation from the ovarian artery as it enters the hilus of the ovary and turns sharply cephalad. Further vascularization of the ovary is accomplished by secondary branches arising from the coils of the spiral artery.

Spiral CT during arterial portography.

RadioGraphics, 1996
Spiral computed tomography (CT) performed during arterial portography offers several advantages compared with portographic studies based on conventional CT technique. Because all hepatic images are derived from a volume data set acquired during a single 24-32-second breath hold timed to coincide with the phase of peak hepatic enhancement, motion ...

Fibrinolysis in Decidual Spiral Arteries in Late Pregnancy

Thrombosis and Haemostasis, 1978
SummaryThe fibrinolytic activity of the intimal cells of decidual spiral arteries and the syncytium of placental villi was studied by electron microscopy in ten normal full-term human pregnancies using a modification of the fibrin slide technique.

LncRNA MEG3 inhibits trophoblast invasion and trophoblast‐mediated VSMC loss in uterine spiral artery remodeling

Molecular Reproduction and Development, 2019
Extravillous trophoblasts (EVTs) migrate into uterine decidua and induce vascular smooth muscle cell (VSMC) loss through mechanisms thought to involve migration and apoptosis, achieving complete spiral artery remodeling.

Spiral CT of Bronchial Arteries in Chronic Thromboembolism

Journal of Computer Assisted Tomography, 1994
Computed tomography study of bronchial artery anatomy and evaluation of dilatation and tortuousity as indicators for pulmonary hypertension and surgical risk in patients with chronic thromboembolism were performed.We retrospectively reviewed contrast-enhanced, thin section spiral CT scans of 39 patients undergoing pulmonary thromboendarterectomy ...

Renal arterial stenoses: spiral CT angiography.

Radiology, 1993
To evaluate the role of spiral computed tomography (CT) in diagnosis of renal arterial stenoses.In 22 patients with suspected renovascular hypertension, spiral CT angiography of the renal arteries was compared with arterial digital subtraction angiography (DSA).

Modified arterial switch operation by spiral reconstruction of the great arteries in transposition

The Annals of Thoracic Surgery, 2000
Spiral relationship of the normally related great arteries (SRGA) has never been reconstructed in an arterial switch operation.From March 1998 to April 1999, 9 consecutive cases of transposition of the great arteries (TGA) family (from 2 days to 1.6 years old) underwent arterial switch operations with SRGA at our hospital.

An In Vitro Model of Trophoblast Invasion of Spiral Arteries

2006
Extravillous trophoblasts invade the uterine wall (interstitial invasion) and the spiral arteries (endovascular invasion), replacing the cells of the vessel wall and creating a high-flow, low-resistance vessel. We describe a model to allow the interactions between the invading trophoblast cells and the cells of the spiral artery to be directly examined.
