A nuchal scan, or ultrasound prenatal screening, is done between weeks 11 and 13 of pregnancy to check for abnormalities. It measures the translucent space in the nuchal crease at the back of the baby’s neck and compares it to the mother’s age to determine the risk of Down syndrome. If there is cause for […]
MRI is an effective cancer screening, especially for patients with dense tissue, but can lead to false positives and trigger claustrophobia. Insurance may not cover it unless medically necessary. Some patients may prefer other screening methods. One of the most common tests to detect cancer is magnetic resonance imaging (MRI). Like other cancer tests, this […]
Bone density scans measure bone mineral density to detect potential fractures or osteoporosis. Results include a T-score (relative to a healthy young adult of the same gender) and a Z-score (relative to others in the same demographic). A negative number suggests bone loss and a higher negative number indicates a higher risk of bone fractures. […]
Kidney scintigraphy is a nuclear imaging method that evaluates blood flow and kidney function. Radioisotopes are injected into the bloodstream and imaged with a special camera. The test takes 30-60 minutes and carries few health risks. It is used to diagnose kidney disorders and detect organ rejection in transplant patients. The procedure is conducted in […]
A Cardiolite scan is a medical imaging study of the heart to look for signs of ischemia. A radioactive tracer is injected and followed as it is absorbed by the heart. The outcome can indicate whether the patient has a heart condition causing ischemia and can also be used to learn more about the patient’s […]
An abdominal CT scan is a non-invasive diagnostic tool that uses X-rays to visualize the body in slices or cross-sections. It is usually painless and takes a short amount of time. The results are not immediate and are interpreted by an experienced radiologist. A computed tomography (CT) scan or computed tomography (CT) scan is an […]
A kidney scan uses a small amount of radioactive material to take pictures of the kidneys and determine their function. It is a safe and simple outpatient procedure that can help diagnose kidney disease or impaired function. Results are usually obtained during a follow-up visit with the doctor. A kidney scan is a test that […]
A thallium scan injects a small amount of radioactive substance into a patient’s vein to create images of the heart or brain to determine if they are getting enough blood. It is often combined with a stress test to determine how well the heart works under stress. The test helps doctors pinpoint people at risk […]
Computed tomography (CT) is a medical diagnostic technology that uses X-ray technology through a computer to create images of internal structures in the body. It is commonly used to diagnose conditions or damage to soft tissue or bone in various parts of the body. CT scans rotate the X-ray source around the targeted tissue to […]
A lung scan is used to screen for lung abnormalities and diagnose conditions such as blood clots and lung cancer. Ventilation and perfusion scans are commonly used to diagnose pulmonary embolism. The type of scan depends on the patient’s symptoms and medical history. Results can determine necessary treatment. A lung scan is a medical test […]
A thyroid scan uses a small amount of radioactive material to diagnose diseases of the thyroid gland. The patient ingests radioactive iodine, which is absorbed by the thyroid gland and evaluated by equipment. The scan can detect if the thyroid gland is functioning normally, its size, and any lumps that could indicate cancer. The scan […]
Mobile CT scans provide cheaper and easier access to diagnostic technology for small healthcare settings, especially in rural communities. They offer the same level of service as static CT scans and can be shared by several facilities to reduce costs. However, stabilizing shock absorbers are needed, and a dedicated crew is required for smooth operation […]
Online spyware scans detect and remove malicious code that tracks user activity, but may not detect all types of spyware. Paid programs are more effective, but some viruses require a complete OS reinstallation. Verify the legitimacy of the scan before using it and carefully check results before uninstalling anything. An online spyware scan is a […]
A service scan identifies potential vulnerabilities on a computer by checking for services running on open ports. It can be used for security checks and testing systems, but also by hackers to find vulnerable computers. Protect yourself by updating antivirus and security software, using a firewall, and being cautious with links. A service scan is […]
Computer networks use cables and devices for communication, with specific access ports for different types of electronic communication. Port scans are used to inspect open ports for suspicious activity and ensure security. Free and commercial port scanning tools are available, but hackers can also use them for infiltration. Port sweeping is another technique used by […]
A coronary calcium scan assesses a patient’s risk of heart attack by measuring calcium deposits in the arteries leading to the heart. Patients with moderate risk are 10-20% more likely to have a heart attack within the next decade. The scan is not conclusive and is used in conjunction with other factors to determine a […]
An octreotide scan uses a radioactive tracer to detect carcinoid tumors and gather information about them. It is safe and involves a technician injecting the tracer into the patient, who then undergoes imaging to track its movement through the body. The patient may be advised to drink water before the test, and pregnant or breastfeeding […]
Online adware scans detect adware and privacy-intrusive software on a computer’s hard drive. Legitimate anti-adware vendors offer free scans, but scams can generate false reports and download more adware. Users should confirm the legitimacy of the anti-adware program before accepting an online scan. An online adware scan is a tool that is used to determine […]
A full table scan is a slow but thorough way to scan a database, used when no index is present. It reads each row and checks for a query or condition set by the admin. An index column records information about the table based on admin preferences, helping to find information in the database. Full […]
Running a malware scan is crucial for keeping your computer free of harmful bugs. Before scanning, update the malware directory. Most software offers basic and custom scan options, with the former being recommended. After the scan, review and remove identified threats. The process is user-friendly. Running a malware scan from time to time is a […]
