Fess On Clear Ct Scans
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. 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
less accurate: While there is controversy about the liberal use of ct scans for the diagnosis of appendicits, it does increase accuracy of diagnosis. There are several parameters on ct scan that are used to diagnose or exclude appendicitis: visualization of the appendix, free fluid around the appendix, blurred fat or fat stranding around the base of the appendix and free air in the area of the appendix. ...Read more
Glucose metabolism: PET with F18 FDG, glucose metabolite, determines glucose metabolism of normal and abnormal structures.For example, sometimes lymph nodes are visualized on CT and do no know whether benign or malignant. In general malignant lesions are more active and have higher metabolism of glucose ...Read moreSee 3 more doctor answers
Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.
Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read moreSee 3 more doctor answers

Clear ct.of.abdomin, cheat xray clear, CBC great, would CT scan show a hematoma on spleen, very worried..

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
CT scan report reveals polyp retention on left maxillary sinus(3*1.5) and bilateral sphenoid sinuses.Doctor has asked for surgery,is surgery necessary?
Sinus polyp: Hello. A maxillary sinus polyp that is in the bottom of the sinus will not interfere with normal sinus drainage pathways. The question really is have you been treated with aggressive medical therapy. This month I treated a patient with sphenoid sinusitis which completely resolved. It may be worth seeing another ENT doctor for a second opinion ...Read more
Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more
Nsclc st4. Diagnostic CT scans used iodine contrast but due to allergy, post treatment CT scans used barium. How accurate/comparable are the scans?
Sodium low&cortisol highi& fatigue&weight loss. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT missed SCLC. Repeat scan?
Look outside lung: Yes CT scans can miss SCLC, especially if the scan is not a 'high resolution' scan with sufficient overlap. However, with 2 negative scans, you should look outside the lung. Head & neck cancers and esthesioneuroblastoma (tumor of nerves that sense smell) can cause this symptom pattern. Though rarer, SCLC can occur outside the lung, as well. A PET scan or whole body bone scan could help. TTYD. ...Read more
Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read moreSee 1 more doctor answer
Different mechanisms: Mri uses magnetic radiation( no x-ray) for anatomic localization and characterization of different parts of body, water and fat constitution of different tissues.Ct uses x-ray to characterize anatomy of body, better for bone than mr.Pet, bone, gallium scans use radio tracers intravenously.Petglucose metabolism of tumors, gallium (infection/tumor), bone scan for fxs, tumors, infection bone metabolism. ...Read more
Endocrine issues + fatigue. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT be missing SCLC. Is repeat scan necessary?
By SCLC, I presume: you mean small cell lung cancer...a type of lung cancer that is aggressive and is a neuroendocrine tumor which can produce ectopic hormones. But it certainly wouldn't be the first thing you would think of if you have "endocrine issues." The thyroid, pituitary, adrenal glands need full evaluation as well as other work-up. If lung CT "clear" would not pursue SCLC as cause. Best wishes:) ...Read more
Endoscopic sinus surgery describes a group of surgical procedures performed using fiberoptic telescopes and other instruments through the nostrils, thus avoiding incisions. The visualization afforded by the endoscopes is far superior to older techniques. The most common indication is for those patients who suffer from chronic or recurrent sinus infections and ...Read more
