A bone scanand a computed tomography (CT) scan are both used to diagnose various bone conditions. The specific use of a bone scan is to diagnose active bone diseases, such asosteoporosis, Paget’s disease or the spread ofcancerinto the bone. ACT scanis a high-resolution X-ray that gives...
While a nuclear attack might target a nation's military infrastructure or population centers, the assault could inflict massive harm to Earth's atmosphere. It's easy to take the air we breathe for granted, but the atmosphere is a vital component of all life on this planet. In fact, ...
Bone scan:A bone scan is used to check your bones for disease or damage. You will get a radioactive liquid, called a tracer, through a vein in your arm. The tracer collects in your bones. Pictures will then be taken to look for problems. Examples of bone problems include fractures (br...
What is osteomyelitis? Osteomyelitis is a severe bone infection. It can develop in any bone, but often involves the long bones, such as your arm and leg bones, or the bones of the spine. Osteomyelitis is caused by different types of germs, such as bacteria or a fungus. ...
What is a nuclear scan of the kidneys? What is vasculitis of the kidneys? Where does filtration of the blood occur within the kidneys? What cleanses the kidneys? What is hypoperfusion of the kidneys? How much blood is filtered through the kidneys daily?
I have noted elsewhere about the dramatic transformation between "the old" and "the new" nuclear medicine that has taken place over the last decade (see my post Nuclear Medicine = New Clear Medicine). The fusion between nuclear medicine and CT was given
A bone scan involves injecting a radioactive chemical, called a tracer, into your blood. A technician takes pictures using special imaging equipment that detects the tracer as it circulates through your blood stream. Accumulations of the tracer show up as dark areas in the bone scan. The trac...
With a CT scan, a neuroradiologist can diagnose or exclude diseases that require urgent ther- apeutic decisions. The most important diagnosis that requires a prompt CT scan of the brain is acute stroke or traumatic brain injury. CT provides information on the state of the brain parenchyma, ...
intensities containing a voxel (3D pixels) grid creates the typical input for image processing. CT scan greyscale intensity depends on X-ray absorption, while in MRI it is determined by the strength of signals from proton particles during relaxation and after application of very strong magnetic ...
