BACKGROUND: Magnetic resonance angiogram (MRA) of the brain is a widely employed non-invasive test to diagnose aneurysms. However, its overall accuracy is less than digital subtraction angiography and is prone to give false-positive or false-negative results. False-negative results can be seen wit...

Hence, for improving the quality of the images with an angiogram, a Morse filter will be implemented (based on the model of the Morse Potential) in a brain's vessels angiogram using both softwares Maple and ImageJ . It will be shown the results of applying a Morse ...
To deliver the contrast agent, a catheter is advanced from the femoral artery in the leg to one of four arteries in the neck that lead to the brain. The doctor steers the catheter through the blood vessels while watching a monitor. A fluoroscope machine, called a C-arm, is an arc ...

Our purpose was to evaluate the utility of surface anatomy scanning (SAS) of the brain with superimposition of MR angiograms in the diagnosis and presurgical planning of superficial cerebral arteriovenous malformations (AVMs). We performed SAS in 15 patients with superficial cerebral AVMs. Two-dime...

In the acute stage, the blood is layered evenly over the convexity of the brain, he explained. At this time, the angiogram will show a uniform displacement of the brain vessels, arteries, and veins, away from the calvarium. The angiographic picture changes the longer the hematoma exists. ...
These patients were prospectively examined by cranial MRI 1–6 weeks after the ictus. The MRI studies were positive in 7 patients (17%). In the 30 patients examined after SAH, 2 studies were positive, showing an aneurysm in one case and a brain stem lesion of uncertain actiology in the ...
while the proposed CGPM was utilized to ensure vessel integrity. In part one, for feature map extraction, we applied the distribution of BRs from the ResU-Net base, which exhibited the optimal segmentation performance of the model. The model training process included both bone segmentation and ves...
