The Incredible Things You Should Know About CT Scans

Learn all the amazing things about CT Scan in this article: Its invention, history…

When your doctor orders a CT Scan to you or one of your acquaintances, ever wondered what it is all about? Or how it will benefit you? 

In the past few decades, CT technology has completely evolved and offers accurate multi-dimensional images of the body parts. It helps doctors to diagnose and treat a variety of severe conditions without any hassles. 

So what is a CT Scan? 

Computed Tomography (CT) imaging is also referred to as Computed Axial Tomography (CAT). The word computed means incredibly robust computer software which is used to analyze the X-ray images created by the CT scan machine. With the help of this program, the radiologists can take each picture, slice generated and rotate it on all sides for different views. They can also zoom in or view it straight on a level of detail that’s extraordinary. 

Axial means the anatomical plane of the body, which has cross-sections from head to toe. In a CT scan, there are many sections of images with depth created in the axial plane by a technique called tomography. This technique shows a cross section through a human body or any solid object that uses X-ray. As a result, they get multiple, highly detailed pictures of the human body in seconds. 

Benefits of CT Scans over traditional X-rays 

CT Scan is an X-ray scan but an advanced one. For example, think of a traditional X-ray as a pair of magnifying glasses or binoculars then a CT is like a telescope.  Where X-rays offer two-dimensional images and a flat image of body parts superimposed on top of each other, in a CT, you can arrange the X-rays so that you can rotate it around the subject and capture multiple sections from many different angles of the body. 

This is the reason why you lay on a table for a CT and then a doughnut-shaped machine has an X-Ray tube that rotates around you. It revolves around your body up to 360 degrees, which allows up to 360 individual pictures of the body that can be taken at slightly different positions. 

With today’s software that makes use of advanced algebra to add, subtract densities at different angles, doctors reckon that there are much more known’s than unknowns for radiologists while reading CT scan images. In fact, you can generate a lot of information about specific areas of the body, especially imperfections than you could before. 

CT Scans: Innovation over the Years 

First invented in the 1970s in England, the CT was earlier used to produce brain images. And prior to this time, taking a glimpse of the body’s soft tissues or structures like infection, blood, tumor was not possible. 

However, now CT is used in a variety of subspecialty of medicine. They are critical in the diagnosis and evaluation of headaches, stroke, head trauma, cancer, stroke, blood clots, appendicitis, pneumonia, and complex fractures. 

The first-generation CT scan took minutes to scan only one cross-section of the body. But today’s CT scans have advanced exponentially to test the entire body and generate hundreds of images in just a few seconds. It hardly ever happens that a CT scan takes more than five minutes. This evolution to generate not just three, but four dimensions add up in getting a  bigger diagnostic picture. 

Why Calcium Score is an Essential Tool in the Management of a Cardiac Disease?

A coronary calcium scan can help you avoid a heart attack. Read to know why and when you need a calcium scan. Also, learn what happens during this scan.

A well-known fact about calcium is that it helps in building bones. But did you know, apart from this, calcium has many other benefits? It enables your blood to clot, your heart to beat, and your muscles to contract. Moreover, calcium helps in detecting your heart health.

With the help of a coronary calcium scan, your doctor can help you avoid a heart attack. A heart test uses a CT scan, which takes pictures of arteries (vessels that transfer blood away from your heart) to check for calcium.

Why Get Calcium Scan Done?

This screening modality holds great promise of detecting heart diseases, as it shows the presence of plaques in your cardiac arteries. Plaque is partially made of calcium and fat. Initially, it’s waxy, and it builds up slowly, but overtime it hardens and is called calcified plaque. These calcified plaques are a warning sign of narrowing of the arteries, or atherosclerosis.  Here’s why they are troublesome:

Like a clog in the pipe, hard plaque blocks your arteries by slowing down your blood flow. This means that many parts of your body don’t get their fill of oxygen. If plaque is accumulated in your arteries, you can experience chest pain and discomfort, known as angina.

Secondly, if plaque breaks open it can lead to a blood clot. This can lead to a heart attack. Your calcium scoring shows how much calcified plaque exists in your heart’s arteries. Henceforth, your doctor can decide if your medication or lifestyle need changes.

When to Get Calcium Scan Done?

Get this calcium test done if you feel you are likely to get heart disease. Your doctor can figure this out with the help of details such as your age, blood pressure, cholesterol level, whether you smoke, and your gender.

What Happens During a Calcium Scan?

For calcium scan, you need to visit a clinic that consists of a CT scanner. First and foremost, the doctor will ask you to avoid caffeine and smoking for up to 4 hours before the test. For the scan, you have to put on a hospital gown, remove your clothes and jewelry from the upper body part.

A few sticky patches will be put on your chest by the person running the scanner. These patches will be connected to an EKG machine that helps the person know when to take the images of your heart. If you are claustrophobic, you will be given the med to slow your heart so better pictures can be taken.

During the calcium heart scan, you have to lie on your back on a table, which slowly moves into the CT scanner. This scanner is a hollow tube that slides into a tunnel and, your head stays out of the tube at all times. When you are done, you are free to go about your day.
