BACKGROUND In studies where cross-sectional images of coronary arteries obtained with different imaging modalities are compared, the importance of correct co-localization and matching of images along the coronary artery longitudinal axis is obvious. However, it appears neglected that correct spatial orientation of the cross-sectional plane may not be obtainable just by rotating the images to en...

STUDY DESIGN For this study, 43 asymptomatic individuals underwent magnetic resonance imaging of the lumbar spine in both supine psoas-relaxed position and supine axial compression in extension. The change in dural cross-sectional area between positions at each disc level was calculated. OBJECTIVES To evaluate the effect of axial loading on asymptomatic individuals, as compared with the effec...

We present a case of lunate fracture diagnosed which was diagnosed with cross sectional imaging. Lunate fractures are rare, and most cases in the literature were reported almost exclusively before the era of computed tomography (CT) and magnetic resonance imaging (MRI). We present the imaging findings in our patient with a brief review of the literature.

Despite progress in noninvasive imaging with computed tomography and magnetic resonance imaging, conventional angiography still contributes to the diagnostic workup of oncologic and other diseases. Arteriography can reveal tumors not evident on cross-sectional imaging, in addition to defining aberrant or unexpected arterial supply to targeted lesions. This additional and potentially unanticipat...

Gallbladder masses are commonly encountered on diagnostic imaging examinations. Distinguishing between benign and malignant conditions is critical, in terms of clinical significance, management, and followup. It is important to be familiar with the differential diagnoses of gallbladder masses, recognize imaging features that are diagnostic for each condition, and understand the utility and limi...

In recent years, there has been a rapid increase in the availability of cross-sectional imaging techniques in veterinary medicine. CT is now readily accessible in many veterinary universities and referral institutions and is gaining acceptance for the investigation of many diseases. The last 10 years have seen a significant increase in CT related clinical research and various comparative studie...

Background Magnetic Resonance Imaging (MRI) is regarded as a non harming and non invasive imaging modality with superb tissue contrast and almost no side effects. Compared to other cross-sectional imaging modalities MRI does not use ionizing radiation. Recently however, strong magnetic fields as applied in clinical MRI scanners have been suspected to induce DNA double strand breaks in human lym...

With the increasing use of abdominal cross-sectional imaging, incidental adrenal masses are being detected more often. The important clinical question is whether these lesions are benign adenomas or malignant primary or secondary masses. Benign adrenal masses such as lipid-rich adenomas, myelolipomas, adrenal cysts and adrenal haemorrhage have pathognomonic cross-sectional imaging appearances. ...

Primary benign and malignant neoplasm of the small bowel are rare. Malignant tumours often present late symptoms resulting in a poor prognosis. Early detection of small bowel neoplasms is desirable but challenging for both clinicians and radiologists. Conventional double contrast enteroclysis was the method of choice in small bowel imaging but is increasingly being replaced by cross-sectional i...

medical imaging has a remarkable role in the practice of clinical medicine. this study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend shiraz university of medical sciences, shiraz, iran. we conducted across-sectional survey using a self-administered qu...
