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.

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

Will hematoma caused by MRI guided breast biopsy limit post biopsy sono or MRI image if suspicious area is very large would sono work inspite of hemat?

Will hematoma caused by MRI guided breast biopsy limit post biopsy sono or MRI image if suspicious area is very large would sono work inspite of hemat?

What is the reason: to look for the lesion on ultrasound after the biopsy? There should have been an ultrasound correlation prior to the MRI biopsy. Yes, the hematoma can limit a post biopsy ultrasound. If ultrasound is necessary, it might be best to wait a couple of weeks so the hematoma can resolve. ...Read more

Is contrast fluid necessary in a CT scan looking for appendicitis? ?

Is contrast fluid necessary in a CT scan looking for appendicitis? ?

depends: Acute appendicitis can be diagnosed with good accuracy by history, physical exam, ultrasound, and non-contrast ct scan of abd/pelvis. Now is some cases, where exam, history and other imaging is not diagnostic and observation of the patient with a surgeon is not possible, more sophisticated imaging, contrasted ct can help. Be well. ...Read more

Lung tumor CT scan with or without contrast?

Lung tumor CT scan with or without contrast?

Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more

Sonogram shows 2.2cm, (2) 1cm in neck lymph's. CT contrast scan doesn't identify lymph's. I'm told its inflammation. CT does not pick up inflammation?

CT can: identify soft tissue inflammation, and can identify lymph nodes. Hard to speculate as to why the CT scan didn't show the lymph nodes, but I suspect if they looked normal the radiologist decided not to mention them. The only way to be certain is to have the radiologist look at the CT and ultrasound side by side and reconcile the discrepancy. ...Read more

Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress? Had CT scan b4

Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress?
 Had CT scan b4

CT only: It is obvious that you wish to avoid ionizing radiation. However MRI is difficiult in imaging lungs of low density tissue, air-tissue interfaces causing artifacts, and respiratory, cardiac, and vascular motions.These are technicalities without any control. Ct is by far the choice for imaging bronchiectasis. ...Read more

I've swollen lymph nodes & normal blood work. My Dr. sent for a CT Scan w/contrast. I'd prefer without. Would a neck CT scan be effective w/o contrast?

Depends: It depends what they are looking for exactly. If your only problem is swollen lymph nodes and symptoms are short term - you may be able to do without it at all. If they are hard, very hard or if there are other symptoms you might want to get it done. CT gives radiation and contrast may pose some threat to kidneys but consider the risk vs. the benefit of finding out what the problem is. ...Read more

+ PPD test, CT scan solitary pulmonary nodule. 5mos after nodule stable/slight increase pet2.9suv bronchoscopy inflammatory no cough doc said remov?

Curious: More information is required. The pet uptake (measured in standard uptake value or suv), is low level, but not low enough to guarantee benignity. Given age and + ppd, i would suspect this could be an active granuloma. Given your age, i would encourage consultation with a pulmonologist and full review of all your records first. Lung surgery is serious business. ...Read more

Do MRI scans usually require an injection of contrast?

Do MRI scans usually require an injection of contrast?

Depends on diagnosis: Usually MRI scans of the spine and joints (shoulder, knees, etc) do not need a contrast injection. Contrast is given for spine MRI scans to search for tumors and postoperative scarring. Mri scans of the brain, abdomen, pelvis can be performed with a contrast injection to help find a tumor, but these scans can also be performed without injection. Breast MRI should be performed with contrast. ...Read more

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs? If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more
