Over many years, there have been huge efforts to develop imaging techniques for identifying plaques and other lesions in coronary arteries. Today, the general tendency is toward minimally invasive or noninvasive therapies and diagnostic procedures. With all the benefits of the noninvasive methods, ...
Excretory MRU is usually preferred over static techniques for the demonstration of non-distended ureters; however, it is contraindicated in severely impaired renal function. As MR urograms are often displayed as maximum intensity projections, a low signal intensity ureteral stone surrounded by high ...
This aided as a motivation for many people who worked on the automated system for the analysis of the retinal images by using the image processing techniques. These features are utilized by the classifiers to grade DR into different stages according to the disease condition and thus indicating ...
Contrast media, also known as medical contrast mediums and contrast agents, are chemical compounds and gases used to supplement medical imaging techniques by enhancing the image results during the medical testing processes. Contrast agents work in combination with either magnetic resonance signal augmentat...
The imaging device allows single photon emission tomography (SPECT),positron emission tomography(PET), X-ray computed tomography, fluorescence and bioluminescence imaging—powerful imaging techniques that provide different information about anatomy and physiological processes happening within the body. With the...
To minimize the impact of some of these trade-offs, a combination of keyhole techniques or modified k-space trajectories, in conjunction with a fluoroscopic (ie, continuous acquisition) mode and a real time reconstruction, permits rapid imaging in a low field system using standard (speed ...

Besides intraoperative imaging, the reduction techniques of the ankle can present challenges22,23. The most common reduction method in the operative treatment of unstable syndesmotic injuries is the conventional bone reduction forceps. Nevertheless, prospective studies have shown that the manual reduction...
