If you're considering a CT or ultrasound scan, it's important to understand the goals of your doctor. Your doctor is able to determine which diagnostic test will work best for you, based upon your symptoms, medical history, and risk factors.
What's the Difference Between CT Scans and MRI Scans
CT scans, also known as X ray imaging procedures, are used to produce detailed images of the human body. It is less expensive and quicker than an MRI. It is less invasive and therefore can be used for larger individuals or people who have claustrophobia.
Magnets are used to take images of the inside of the human body. They are very sensitive and can detect disease or injury. It can be used for detecting cancer tumors, organ damages and vascular abnormalities such as stroke.
Ultrasound, on the other hand, uses high-frequency sound waves to create an image of your body. It can be used to visualize bones, muscles and other internal organs and is often a part of prenatal care.
Contrary an MRI scan, an ultrasound can be safely performed on a pregnant woman as long she does not have any allergies or medical conditions which could impact the results. Sometimes, a contrast agent is added to the ultrasound in order to enhance the images that the machine produces.
A ct-scan is similar to an image taken with X rays. However, it offers a better resolution and allows the scan to be focused on the exact area. It is faster than an MRI.
It uses less ionizing rays than an MRI. Also, it is easier on your kidneys. It can also be a good option for patients allergic to liquid contrast agents used in most CT scanners.
Ultrasound can be a better option for many people because it is less expensive and has a lower risk of harm to the patient than a CT scan. It's less invasive than MRI and exposes the patient to ionizing rays, making it safe for pregnant women and kids.
A CT scan is not recommended when pregnant as the amount of radiation could be harmful to your developing baby. An ultrasound can be used instead of a CT to help reduce these risks.
Contrast agents can harm the unborn baby. Therefore, pregnant women should avoid having an MRI. This is not recommended to anyone taking drugs, or who has a weak immunity system. It may increase the chances of you getting sick.
Patients who have suffered a heartattack or another traumatic event, and are looking for a clear image of their internal anatomy in order to determine if surgery is needed, may benefit from a CT scan. It is also helpful in determining the severity of brain injuries, and for imaging the abdomen to diagnose conditions like cancer or appendicitis. It's also an excellent choice for those who have suffered from a stroke. It can identify the cause, and allows treatment to be started immediately.

How To
What is the Healthcare Industry Value Chain?
The healthcare industry value chain consists of all the activities involved in providing healthcare services to patients. This includes all business processes at hospitals and clinics. It also includes supply chains that connect patients to other providers like pharmacists and insurance companies. The end result is a continuum of care that begins with diagnosis and ends with discharge.
The value chain consists of four major components.
-
Business processes - These are the tasks performed throughout the whole process of providing health care. A doctor might conduct an exam, prescribe medication and send a prescription to a pharmacy. Each step of the process must be completed accurately and efficiently.
-
Supply Chains are all the organizations responsible for making sure the right supplies reach their intended recipients at the right time. A typical hospital has many suppliers. They include pharmacies as well lab testing facilities, imaging center, and even janitorial employees.
-
Networked organizations - These entities must communicate with each other in order to coordinate. Hospitals often have several departments. Each one has its own phone number and office. To ensure that everyone is up to date, every department will have a central point from which employees can access updates.
-
Information Technology Systems (IT) - IT is essential in order for business processes to run smoothly. Without it things would quickly fall apart. IT can also be used to integrate new technologies into a system. Doctors, for example, can connect to a secure internet connection to access electronic medical records.
