CT THORASIC SPINE

CT thoracic spine scans are non-invasive imaging tests that take advantage of x-rays and computer technology to provide detailed, cross-sectional views of the thoracic spine. This is often used to diagnose and keep track of various conditions affecting the thoracic spine like herniated discs, spinal fractures, and spinal tumors.  

What is a CT Thoracic Spine Scan?  

A CT thoracic spine scan is the procedure done to the patient where x-rays and computer technology are applied to acquire detailed images of the thoracic region of the spine. The patient lies on a table, which is then slid into a big round machine that looks like a doughnut. The machine rotates around the patient, taking x-ray pictures from different angles. All the captured images are later constructed into detailed x-rays of the thoracic spine. 

Types of CT Thoracic Spine Scans 

Different kinds of scans can be performed on the thoracic spine, including: 

• Non-Contrast CT scan: Best used when checking for fractures or bone-related problems. This scan does not require a contrast dye. 
• CT Myelogram: Contrast dye is used on this test in order to more accurately show the spinal cord and the nerve roots, this is also known as a CT myelogram.  
• Contrast CT scan: The use of soft tissue structures like discs and nerves require the use of contrast dye therefore this test falls under the category of contrast CT scan. 

List of Parameters Considered During CT Thoracic Spine Scan

For the scan, the following parameters is regarded:  

• Bone density as well as the valuable structure is noted.  
• The condition and height of the disc is also observed.  
• The spinal canal condition is also noted along with the width.  
• Condition of the nerve root alongside the spinal cord.  
• Soft tissue structures such muscles and ligaments. 

Reasons For Taking CT Thoracic Spine Scan

CT thoracic spine scans may be necessary due to the following:  

• Bulging disks  
• Fractures of the spine  
• Tumours in the spine  
• degenerative disk disease 
• Spinal stenosis  
• Spondylolisthesis 

When and Who Needs to Take a CT Thoracic Spine Scan? 

It may sometimes be indicated as part of the workup for patients suffering from: 

• Upper or middle back pain with associated numbness 
• Weakness or paralysis in the limbs either in the upper or lower quadrant. 
• Gait imbalance or controlled walking difficulties 
• Any recent trauma or surgical intervention involving the thorax 
• Suspected infections or neoplasm(s) involving the spinal column 
• Disc herniations, disc degeneration, or spondylitis changes with canal or foraminal stenosis. 

It is most often indicated for adults and paediatric populations with suspected thoracic spine pathology. 

Benefits of Taking the Test

CT thoracic spine scans are easy and have advantages such as:  

• Less Invasive thus making it virtually pain-free.  
• Clear images of the spine are obtained.  
• Varieties of illness can be identified and also closely monitored.  
• Care and treatment of ailments related to the spine becomes easier. 

Illnesses Diagnosed with CT Thoracic Spine Scan

Several conditions are diagnosed using CT thoracic spans. These include:  

• Bulging disks.  
• Fractures of the spine.  
• Tumours in the spine  
• Diseases related to disks.  
• Stenosis of the spine.  
• Spondylolisthesis. 

Preparing for a CT Thoracic Spine Scan

Patients are required to: 

• Take off all jewellery and any clothing that has a metal fastener.  
• Put on a hospital gown or other loose-fitting clothing.  
• Refrain from eating and drinking a few hours prior to the test.  
• Notify their doctor or the technician of any allergies, other medical conditions, or medications being taken. 

Pre-requisites 

No specific pre-requisites CT thoracic spine scans, however, patients might be needed to:  

• Not eat for several hours before the test.  
• Refrain from taking specific drugs or substances. 

Best Time to Take the CT Thoracic Spine Scan 

CT thoracic spine scans can be done at any time. However, they are scheduled at times when patients are most comfortable and able to stay still for the duration of the test.  

Eligibility 

CT thoracic spine scans are often advised for adults and children who are likely to have a thoracic spine problem. On the other hand, some patients with other medical conditions like kidney disease or pregnancy may need to undergo different tests. 

Procedure for Taking a CT Thoracic Spine Scan 

In general, a thoracic spine CT scan follows these actions: 

1. Preparation: After removing metal objects, the patient will lie supine on the CT table. 
2. Scan: The patient is positioned on a table which is automated, meaning it will move into/from the scanner automatically. 
3. Usage of Contrast Dye: A contrast medium may be given intravenously to enhance the differentiation of some soft tissue components. 
4. Completion of Scan: The scan is carried out, after which the patient is taken out of the machine. 
5. Results: A series of images are taken, and these images will be processed through reconstruction software and subsequently interpreted by the radiologist. 

Caution Before Taking the Test 

Inform patients to bring it to the attention of their doctor or the technician for any of the following issues: 

• Allergies or other health issues 
• Any form of drug or substance they might be using. 
• Pregnancy or the possibility of being pregnant. 
• Anxiety disorders including but not limited to claustrophobic tendencies.
