The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Ultrasound guided or CT guided biopsy of liver. Which is more accurate?

Ultrasound guided or CT guided biopsy of liver. Which is more accurate?

Both are accurate : Liver biopsies are performed for both focal liver lesions and nonfocal generalized liver disease playing a key role in the diagnosis and prognostication of various diffuse liver dysfunctions. Ct-guided procedures are generally reserved for tissue sampling of focal hepatic lesions, not accessible by ultrasound. ...Read more

Have had abdominal ct-guided biopsy and 2 path labs can't agree. What next?

Is the difference in: Opinion clinically significant? Two pathologists, like any two people may have slightly different view of a given tissue. It is for your doctor to discuss the matter with both parties to see if the differences are just terminology/semantic or do the opinions differ enough to affect diagnosis and treatment. If latter, it would be good to consult a pathologist at a large academic center. ...Read more

They found a spot or scar on my left lung. After 6 months they want to do a CT guided needle biopsy. What is this?

They found a spot or scar on my left lung. After 6 months they want to do a CT guided needle biopsy. What is this?

CT guided biopsy: When a spot is close enough to the chest wall, interventional radiologists are able to use ct scan pictures to guide a small needle into a spot. Normally, when a spot is found, we follow it with ct scans. It it looks like it's getting bigger, we plan for a ct guided biopsy to find out what it is. When the spot is away from the chest wall we consider bronchoscopy vs surgical removal. ...Read more

Can a CT guided spine biopsy of L3 result in scar tissue? Had biopsy 3 weeks ago had a burning pain in my right anterior thigh one day later. Serious?

Yes, but consider...: Yes, a ct biopsy can result in scar. However, the L3 nerve root supplies sensation to the anterior thigh. Most likely there is swelling around or irritation of this nerve root which could be expected after this procedure. If it doesn't resolve within a couple weeks, see your md. ...Read more

Thymus: May be the source of the mass, and it could be invasive ornon-invasive. Thymomais associated with rheumatologic/auto-immune conditions. Lymphoma is another prospect, more rare are germ cell tumors (teratoma) and substernal thyroid. Sarcoid can involve any node bearing areas. ...Read more

Can a person have CT guided nerve root injection if she is on apixaban?

Can a person have CT guided nerve root injection if she is on apixaban?

Usually not: Most practitioners who perform that procedure instruct the pt to d/c the drug several days before. These days, anyone who does that procedure is expected to have a written protocol that includes such details. If you're not asked whether you're on apixaban or other antithrombotics before the procedure & aren't given preprocedure & aftercare printed instructions, call a big time out. ...Read more

What is the definition or description of: ct-guided drainage of hematoma or fluid collection?

What is the definition or description of: ct-guided drainage of hematoma or fluid collection?

CT is a 3-D scan....: That provides an x-ray cross-sectional view of the scanned body "slice, " allowing any blood or fluid collection to be accurately hit by a long needle or tube that drains off the fluid. The cat or ct scan allows much more accuracy than a "blind" poke with a needle, and also allows the doctor doing the fluid evacuation to see what structures lie along the needle path (more safe; less trauma). ...Read more

What is the definition or description of: ct-guided fine needle aspiration?

Minimally invasive: A ct guided fine needle biopsy is performed by an interventional radiologist and in ideal situation will have a cytopathologist evaluating the samples at the bed side. The ct is used to guide the needle to the target to acquire a sample. It is usually done with local but sedation can be used . In the right hands it is a very high yield test. Ask your team what their success rate is! ...Read more

Is it possible to have a normal negative CT scan yet still have lymphoma or will the CT scan determine some abnormality which then leads to a biopsy?

Yes to both.: You can have an indolent lymphoma - abnormal immune cells in the lymphatic system - but in such a stage that the lymph glands aren't yet (or won't be) enlarged. The CT scan only points out glands that are enlarged or suspicious in the region that was scanned (an enlarged gland in the neck will not show up on a CT scan of the chest). Without an abnormal/enlarged gland, there's nothing to biopsy ...Read more
