Endoscopy Vs Ultrasound
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
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
What are the chances an ultrasound, Mri/mrcp, ercp, and ct scans or imaging miss advanced liver cancer?
If it is tailored: For liver mass, and technically adequate(i.e. no artifacts that might obscure anatomy), it would be nearly impossible to miss a large liver tumor. ...Read more
Can normal CT scan, stool and blood tests, colonoscopy, gallblader us and hida scan, upper endoscopy (gerd, gastritis) rule out pancreatic cancer?
What's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?
Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...Read more
Whats the difference between training for diagnostic medical sonography or vascular ultrasound tech?
Vascular ultrasound : Early training is essentially the same. Later training will focus on vascular or general depending on the program. Many technologist train in both. ...Read more
Different no better: A thyroid nuclear uptake and scan is a functional test of your thyroid. It is useful in differentiating causes of thyrotoxicosis (excessive amounts of thyroid hormones in the body). A thyroid ultrasound is better to assess the anatomy of the thyroid gland and for guidance if biopsy is needed. ...Read moreSee 2 more doctor answers
Thickened stomach wall is seen via ultrasound. What is the best way of further investigation ? Is it MRI, CT Scan or endoscopy?
Endoscopy: The MRI or CT scan will not allow physicians to see what the surface of the stomach looks like. Endoscopy is the only way that is performed. Also, during endoscopy, a biopsy may be obtained to determine (definitively) if there is any pathology (anything abnormal) in the stomach. Most likely, though, without symptoms, this finding (thickened stomach wall) is benign. Good luck, thanks for asking HT. ...Read moreSee 1 more doctor answer
Which is better for detecting ovarian tumors ultrasound or cat scan, my pelvic ultrasound said solid mass, CT said no mass?
Complimentary: Ct ; ultasound are complimentary imaging modalities. For smaller masses in appropriate location ultrasound may have an advantage especially if done transvaginally. For larger masses ct may have the advantage of not being blocked by bowel gas and being less degraded by large body habitus. More specific info in your case would be helpful. Size of mass? How was the sono done? Ct with oral and IV cont. ...Read moreSee 1 more doctor answer
CT scan: A hiatal hernia is a hernia or enlarged opening in the diaphragm where the esophagus comes through into the abdominal cavity. It can be seen on endoscopy, some xrays, and ct scans. A hida scan is a function test of the gall bladder and it will not show a hiatal hernia. ...Read moreSee 2 more doctor answers
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 moreSee 3 more doctor answers
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
Give indication: Xr, and anything without direct visualization give an indication as to what is suspected. The symptoms, the exam and the history makes a doctor arrive at a diagnosis as the most likely thing. If in doubt, then direct visualization needed. I hope that gives you reassurance. ...Read more
