CT BRAIN + VENOGRAM

A CT (computed tomography) scan of the brain and venogram is a specialized imaging test that captures a regular CT scan of the brain and combines it with a venogram or an imaging test that uses X-rays and contrast dye to visualize veins in the brain. It is used for visioning the brain and its blood vessels, especially the veins, to diagnose and follow numerous problems such as blood clots, strokes, and even vascular malformation. 

What is a CT Brain + Venogram? 

Like many other CT scans, a CT brain and venogram combines X-ray imaging and computer technology to yield high-quality pictures of the head's tissues and blood vessels in cross-section. During this test, a contrast dye is injected into the patient's arm, which marks the blood vessels in the brain and makes it possible for the images to be viewed in the CT scan. The venogram portion of the exam employs X-rays to take pictures of the contrast dye flowing through the veins in the brain. These images show the blood flow and blockages in the veins. 

Types of CT Brain + Venogram 

There are different classes of CT Brain + Venogram which include: 

• Without contrast CT Brain + Venogram: In this case, there is no use of a contrast medium, and it is mostly done to check the brain and the blood vessels in it without marking any particular areas. 

• CT scan of the Brain with Contrast, CT Venography: This scan utilizes contrast dye to visualize the brain and head circulation, with the blood vessels of the head being examined in more detail. 

• CT scan of the Brain with Motion, CT Venogram: This scan captures multiple images over a period of time to assess blood flow, blockages, and other vascular abnormalities. 

List of Parameters Considered During the CT Brain + Venogram

The following parameters appear to be the most important during CT Brain + Venogram examinations: 

• Examining blood supply, including its circulation and any possible obstruction. 

• Presence of stroke and blood clot. 

• Cerebral angiography and vasography conditions. 

• Presence of abnormal AVM type malformations. 

• The presence of cysts or brain neoplasms. 

Reasons for Taking a CT Brain + Venogram

The examinations are used primarily for: 

• Monitoring and diagnosing the blood clot and stroke. 

• Judging the state of the vessels of the brain. 

• Diagnosing and overseeing AVM type malformations. 

• Monitoring brain cysts or tumours. 

• Judging the condition of the head after an injury.

When and Who Needs to take a CT Brain + Venogram? 

A CT Brain + Venogram may be recommended for Saw patients’ symptoms like: 

• Intense migraines 

• Confusion or lack of awareness 

• Facial or limb weakness or numbness 

• Vision alteration or diplopia 

• Convulsions 

This exam is performed to identify and assess the progression of: 

• Clots in blood vessels or strokes 

• Vascular anomalies, such as AVMs 

• Cerebral vasculitis 

• Tumours or cysts in the brain 

Benefits of Taking the Test

The advantages of a CT Brain + Venogram are: 

• Fast and painless examination of the head and its blood vessels. 

• Detailed brain and blood vessels images are obtained. 

• It can be used to check for blood clots, stroke, and AVM type vascular changes malignancy as well as check-up of the various other conditions. 

Illnesses Diagnosed with CT Brain + Venogram

A CT Brain with Venogram can diagnose and keep track of the following issues: 

• Strokes or blood clots 

• AVMs or other types of Vascular malformations 

• Inflammation of blood vessels in the brain or Cerebral vasculitis 

• Tumours or cysts in the brain 

• Moyamoya disease which is caused by narrowing of blood vessels in the brain 

Preparing for a CT Brain + Venogram

Patients may have to do the following before getting the CT Brain + Venogram: 

• Undergo blood tests to evaluate the function of their kidneys 

• Refrain from certain medications which can interfere with kidney function 

Best Time To Take A CT Brain + Venogram 

Anytime you feel comfortable will work for a CT Brain + Venogram, however, it is recommended that the procedure be done immediately after symptoms develop or a diagnosis is given. 

Eligibility 

A CT Brain + Venogram scan is usually suggested for patients who: 

• Have one or more symptoms that include, but not limited to, severe headaches, confusion, or any weakness in the body. 

• A history of blood clots, strokes, or vascular malformations. 

• Family history of moyamoya or any other medical condition. 

Procedure for Taking a CT Brain + Venogram 

The important steps involved in a CT brain plus a Venogram procedure are the following: 

1. Preparation: The patient must remove jewellery, glasses, or clothes with metal parts and lay on the table that shifts inside the CT scanner. 
2. Contrast dye injection: The doctor starts an IV line in the arm and injects the contrast dye through the line. 
3. CT Scan: X-Ray images of the patient’s brain and blood vessels are captured by the CT scanner and the contrast dye moves through the veins. 
4. Venogram: While the contrast flows through the brain’s veins, the X-Ray images capture it enabling the doctor to perform the venogram component of the test. 
5. Image analysis: A Radiologist reviews the images to uncover and track any underlying issues that may surface. 

Caution Before Taking the Test 

Prior to a CT Brain + Venogram, patients are advised to: 

• Tell the technologist about any medications that are being taken, allergies, or any medical conditions 

• Refrain from certain medications that could cross interfere with the contras dye 

• Be ready to remain in one position for predetermined duration and comply with directions during the procedure
