What is reformatting in CT?
Reformatting involves computer interpolation of two-dimensional multislice images acquired during routine axial CT scanning in order to generate a three-dimensional volume of data. From this block of data, new images are created and displayed in any desired plane.
Can CT scan See spinal cord?
Using CT, the bony structure of the spine vertebrae is clearly and accurately shown, as are intervertebral disks and, to some degree, the spinal cord soft tissues.
What does a CT myelogram show?
A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography (CT) to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.
What is a multiplanar MRI?
Multiplanar reconstruction (MPR) is a method of displaying three-dimensional datasets. The authors assessed the usefulness of MPR for evaluating knee MRI datasets by comparing readers’ performance using MPR and conventional film MRIs. Methods: Eight patients with internal derangement of the knee were studied.
What is the difference between MPR and MIP?
MPR = multiplanar reconstruction, MIP = maximum intensity projection, SSD = shaded-sur- face display, Vol Rend = volume rendering.
What does a CT of the lumbar spine show?
A CT scan of the spine may be performed to assess the spine for a herniated disk, tumors and other lesions, the extent of injuries, structural anomalies such as spina bifida (a type of congenital defect of the spine), blood vessel malformations, or other conditions, particularly when another type of examination, such …
Is myelogram better than MRI?
In that case, radiologists typically order a myelogram as an alternative to the giant magnet known as an MRI machine. Myelograms can outperform MRIs: In addition to the fact that MRIs aren’t safe for some people, myelograms can perform better than MRIs in analyzing some areas of the body.
How painful is a myelogram?
How does it feel? You will feel a quick sting from a small needle that has medicine to numb the skin on your back. You will also feel some pressure as the long, thin spinal needle is put into your spinal canal. You may feel a quick, sharp pain down your buttock or leg when the needle is moved in your spine.
Will a CT scan show a herniated disc?
A computerized axial tomography scan (a CT or CAT scan) or a magnetic resonance imaging test (an MRI) both can show soft tissue of a bulging disc. These tests will show the stage and location of the herniated disc so you can receive proper treatment.
What is multiplanar reconstruction in CT?
Multiplanar reformation or reconstruction (MPR) involves the process of converting data from an imaging modality acquired in a certain plane, usually axial, into another plane 1.
What is a lumbar CT scan?
A CT scan, commonly referred to as a CAT scan, is a type of X-ray that produces cross-sectional images of a specific part of the body. In the case of a lumbar spine CT scan, your doctor can see a cross-section of your lower back.
What is the CPT code for lumbar tomography with contrast?
For example, in this scenario it is appropriate to report code 72129 Computed tomography, thoracic spine; with contrast material and code 72132 Computed tomography, lumbar spine; with contrast material with -26 modifiers to designate that only the professional components are being reported.
How is a CT scan of the thoracic spine performed?
The CT studies are performed and the patient is then admitted to the hospital. Later the same day, the trauma service orders CT scans of the thoracic and lumbar spine. These are performed by reconstructing the CT scan data from the previously acquired CT scans of the chest, abdomen and pelvis.
When do you report a thoracic and lumbar spine reconstruction?
If reconstructions of the thoracic and lumbar spine are ordered and the images reconstructed from the original CT data sets, it is appropriate to report the professional components for interpretations of the spine CT scans; the technical component is not reported, as it is considered included in the initial CT procedure.
