What are the major diagnostic tools to fight cancer?

An accurate diagnosis of cancer is critical in planning cancer treatment. Learn…

One of the essential aspects of successful cancer treatment is an early diagnosis. This treatment is more effective if the doctors get a comprehensive and accurate evaluation at the onset. The process includes a physical exam, the patient’s history of health, and diagnostic scans. 

The cancer presence is confirmed with an accurate diagnostic test, which is necessary to plan the treatment. These scans are also used to detect how far advanced the tumor is and to check the effectiveness of the treatment. 

Cancer Diagnosis: Procedure 

An imaging scan is an effective way to detect cancer. Diagnostic scans like X-rays and MRIs allows a physician to view abnormal masses or internal injuries. Additionally, these scans can determine whether a tumor is benign or malignant. 

When a scan shows an irregularity, the doctors surgically employs image-guided tools to check the anomalies in the body parts, get rid of a small sample tissue for biopsy, and evaluate the grade of disease if its cancer. 

Cancer Diagnosis: Tools 

Cancer treatment requires cutting-edge tools to detect tumor cells, which are essential in the fight against cancer. 

MRI  

MRI produces highly detailed images of internal organs with the help of a large magnet system. It doesn’t use harmful radiation and is used to detect cancer at the onset. 

CT Scan 

Computed Tomography offers amazingly accurate 3D images of tissues and organs. It is commonly used in detecting and staging various cancers. 

Digital X-Rays 

The most commonly used diagnostic imaging tool for detecting cancer is radiography. It helps diagnose cancer in its early stages. The radiography uses electromagnetic energy beams that produce images of bones, tissues, and internal organs. This method is mostly used to diagnose bone cancer and lung cancer. 

Ultrasound 

Highfrequency sound waves produce images of tissues and internal organs. Ultrasound, though frequently used in pregnancy, is also instrumental in detecting tumors in the urinary and reproductive system. 

Digital Mammography 

This procedure involves low-dose X-ray of the breasts used to detect breast cancers and check for abnormal growths in the breasts. Followed by a biopsy, it analyzes and questionable tissue. 

 

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.
