Computed Tomography (Definition)

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

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...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
