Ct Scan Results Same Day
I had a CT scan with contrast dye and a mrcp with contrast on the same day-- 4hours apart. Also, scheduled a CT guided biopsy 2 days later. Any issue?

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
Different eyes.: Check the films first to make sure they are reading the same study! two reporters never give exactly the same story, but the facts are often the same. You might be surprised at how similar two "different" reports actually are. A good radiologist knows what to say and a good clinician knows what to look for. ...Read more
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
What does it mean when CT scan report said one nodules slightly conspicuous. Slice selections are favored but consider follow up CT scan in 3 months?
Sampling artifact: Each ct image represents a portion of the body and has a thickness, usu 5mm. Slice selection artifact occurs when the abnormality is nearly the same size as the thickness of the image. If the abnormality occurs completely in the slice, it is seen well. However, if it bridges 2 slices it may not be seen well in either. A repeat 3 months can would allow evaluation for interval growth or resolution. ...Read moreSee 1 more doctor answer
Anatomic/physiologic: Pet scan involves intravenous injection of radio tracer usually f18 fdg.Imaging of whole body occurs for localization of areas of increased glucose metabolism. Malignant tumors usually most active.Ct scan involves x-ray and performs anatomic imaging of parts of body usually head, chest, abdomen, pelvis, or extremities. Pet?Ct combines imaging modalities for anatomic localization of areas of uptake. ...Read moreSee 1 more doctor answer
Looking at bone: The CT scan is better than MRI in detecting bone fractures or pathologies involving the bone. MRI is better at distinguishing between soft tissues. CT scan is also faster & quieter than MRI. However, the CT scan uses radiation & there has been an explosion of radiation-related conditions in recent years. Each modality measures different things. So ask your doctor if the test is needed or not. GL. ...Read moreSee 1 more doctor answer
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
Would a CT scan show gallstones because my CT scan came back clear. Also, would a CT scan combined with urine tests and blood tests detect gallstones?
Bad idea to have contrast CT & contrast MRI in same day (i.e., too much, different contrast at once)? Should I request creatinine test 1st?
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
Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more
Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?
Yes: The ct scan will consist of at least 3 parts. A very low dose scan to show the anatomy and allow for planning of the full ct scan. The next scan is the "real" scan without contrast. Then there will be at least 1 scan with contrast, usually when the veins are most opacified, at about 70 seconds after the start of the injection. However, some contrast scans have multiple phases for some anatomy. ...Read moreSee 1 more doctor answer
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
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

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
Mri shows three lobulations in bone above knee. Bone scan says everything ok. How could mri and bone scan show two different results?
Different studies: The meaning of "lobulations" in the bone on an MRI study is uncertain. This may mean an osteophyte, cortical thickening, old trauma, a normal variant, or something else. The bone scan measures bone chemistry and activity such as repair of the bone. When the bone scan is normal with these findings on MRI, it means normal bone chemistry, and indicates a none serious problem. ...Read moreSee 1 more doctor answer
