abstractneuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. it is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. neuroimaging modalities include x-ray computed tomography (ct), magnetic resonance imaging (mri), single photon emis...

Currently, inflammation is considered to be the central player in the pathogenesis of atherosclerosis. It leads to the formation of multiple plaques in the arterial beds including coronary vasculature. Recent studies using the latest imaging techniques have shown that in patients with acute coronary syndromes (ACS) multiple plaques are ruptured and have thrombus formation on them. Various facto...

As “time is brain”, acute ischemic stroke is considered a medical emergency. With the introduction of thrombolytic therapy and availability of modern neuroimaging modalities, timely diagnosis of an ischemic lesion, exclusion of intracerebral hemorrhage, assessing the degree of brain injury, and evaluation of cerebral vasculature is necessary in acute stroke management. Various neuroimaging tech...

There is a diversity of modalities available for the imaging of soft tissue and skeletal sarcomas. However, conventional radiography remains the first line imaging modality in the diagnostic work-up, as it provides superior spatial resolution for the evaluation of bone trabecular detail. This article focuses on the advanced imaging modalities of computer tomography, magnetic resonance imaging, ...

The purpose of this study was to evaluate the diagnostic capability of imaging modalities used for preoperative mesenteric-left portal bypass ("Rex shunt") planning. Twenty patients with extrahepatic portal vein thrombosis underwent 57 preoperative planning abdominal imaging studies. Two readers retrospectively reviewed these studies for an ability to confidently determine left portal vein (PV)...

Recent research in endodontics has highlighted the need for three-dimensional imaging in the clinical arena as well as in research. Three-dimensional imaging using computed tomography (CT) has been used in endodontics over the past decade. Three types of CT scans have been studied in endodontics, namely cone-beam CT, spiral CT, and peripheral quantitative CT. Contemporary endodontics places an ...

In the past, the medical profession realized that algorithms for certain patient’s complaints and symptoms needed to be defined. Imaging modalities were increasing in type and number, creating confusion in determining the best method of examining patients. The number of diagnostic imaging choices and other testing procedures forced the development of the algorithms. There was a danger of patien...

Atherosclerosis is currently considered to be an inflammatory and thus a systemic disease affecting multiple arterial beds. Recent advances in intravascular imaging have shown multiple sites of atherosclerotic changes in coronary arterial wall. Traditionally, angiography has been used to detect and characterize atherosclerotic plaque in coronary arteries, but recently it has been found that pla...

The diagnosis of prosthetic valve endocarditis continues to present a diagnostic challenge, due to the lower sensitivity of the modified Duke criteria and a higher percentage of negative or inconclusive echocardiography results. Diagnostic delay might result in significant morbidity/mortality. Imaging modalities like 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/comput...
