Strictly speaking, the physics of CT scanning involves attenuation of the x-ray by tissues in a manner not always exactly congruent with density differences. Hyperattenuation is a better term than hyperdense for more white and bright on the image.
Hyperdense: More dense than brain. Hyperdense on CT shows more white and bright, like bone. Hyperdense abnormalities may be blood if acute, calcium, metal artifact, some tumours
What else can I help you with?
A ct scan was performed on my son's head the patchy attenuation was in the pons area of the brainstem how serious is this and how should he follow up please?
Low attenuation can mean different things. Was it a CT scan or MRI, do you know if they used contrast. An area with low attenuation needs to be re-evaluated to see what it is. Why did he have the scan? Did he have a trauma/injury? Was he having headaches or other symptoms? What else did the doctors tell you?
What are patchy areas of low attenuation in the brainstem mean?
Since 'attenuation' is used, I assume they're talking about CT. Low attenuation means there's not as much tissue in that area blocking the x rays of the CT scanner, which could indicate atrophy in that region I believe. Yes a CT scan was performed on my son's head. It said the patchy attenuation was located in the pons area of the brain stem. How serious is this and how should he follow up?
Can you smoke before a ct scan?
Can I smoke before ct scan
What medications should not be taken after a Contrast CT Scan?
There are no generally contraindicated medications after a contrast enhanced Ct Scan.
What does hyper attenuation mean?
Hyper attenuation refers to an excessive reduction in the intensity of a signal, often observed in imaging technologies such as X-rays or CT scans. It occurs when the material being imaged absorbs or scatters more radiation than expected, leading to areas that appear overly dark or lacking detail on the resulting images. This phenomenon can result from dense materials or pathological changes in tissues, complicating diagnosis and interpretation.
Preparation for a ct scan abdomen?
should you eat before having a ct scan of the chest and abdomen
What is the computerized x-ray imaging in the transverse plane?
CT scan
What does hypo-attenuation mean?
Hypo-attenuation refers to an area in medical imaging, such as a CT scan, where the tissue appears less dense compared to surrounding tissue. It can indicate a pathology or abnormality, such as a fluid-filled area like a cyst or edema. Further evaluation may be needed to determine the underlying cause.
What does CT scan stand for?
cat scan
Would an abdominal CT scan detect an ulcer?
No, you cannot see an ulcer on a ct scan.
