6 paź 2022 · This is a radiological term that refers to the hazy gray areas on images made by CT scans or X-rays. This article will provide information about lung opacity, whether it means you have lung cancer,...
1 maj 2021 · A lung opacity is a frequently used term by radiologists on chest X-rays and essentially means a white spot of uncertain significance. The lungs are normally black on a chest X-ray so anything that blocks the X-rays from getting through will look white on an X-ray.
17 lis 2016 · Key Points • Using contrast enhancement and flow patterns to identify the cause of a non-diagnostic CTA. • Recognize life threatening causes of altered contrast dynamics such as cardiac asystole. • Non-target vessel opacification may hold key to underlying pathophysiology.
The current review article outlines normal and abnormal intravenous contrast dynamics, discusses how to recognize etiologies of non-diagnostic scans, and ultimately addresses techniques to overcome obstacles towards obtaining normal contrast opacification of the target vessel.
23 lut 2023 · Atelectasis: opacity accompanied by signs of volume loss. Diffuse or multifocal airspace disease. Pulmonary edema: CHF and non-cardiogenic pulmonary edema. Pneumonia: bacterial, viral, Mycoplasma, Pneumocystis. Hemorrhage: trauma (contusion), immunologic (Goodpasture’s), bleeding diathesis, pulmonary embolism.
Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is.
1 lis 2007 · Computed tomography urography (CTU) is a relatively new diagnostic imaging examination providing comprehensive evaluation of the upper and lower urinary tract. Multidetector CT (MDCT) enables isotropic or near-isotropic high-quality multiplanar image reconstruction.
