Alzheimer's disease affects 5.8 million Americans. It is among the top causes of dementia. Alzheimer's is challenging to diagnose in the initial stages because it does not exhibit any symptoms until later stages. Symptoms such as memory loss appear after neurodegeneration (which takes years or decades) has already taken a toll on cognition and memory.   Clinical trials that aim to reverse or slow down cellular damage brought about by Alzheimer'sdisease have failed repeatedly. Could it be because the drugs are administered too late? Researchers and scientists are yet to find out. The only way to ascertain the hypothesis is to find a way to diagnose Alzheimer's disease in people with zero symptoms then test the drugs.   Scientific Developments for Alzheimer Diagnosis   Biological markers rely on tests of cerebrospinal fluid and brain scans, e.g., blood tests, MRI brain scans, cerebrospinal fluid tests, genetic tests, and PET brain scans. Biomarker tests show how the

COVID-19 is often diagnosed through RT-PCR testing. Now some experts are arguing that CT scans can help to diagnose Covid-19 . But others disagree with them. The covid-19 epidemic continues to spread all over the world, killing many people as nations strive to find cure or vaccination. Diagnosing people with SARS-CoV-2 early is key to combating the spread of the disease. Once you are diagnosed, you can limit your physical contact with other people and slow down its spread. To many people, reverse transcriptase polymerase chain reaction (RT-PCR) is the gold standard for Covid-19 diagnosis. RT-PCR is a molecular biology technique that identifies material specific to the SARS-CoV-2 virus. However, RT-PCR does not provide 100% accuracy, which has raised concerns about the false-negative and false-positive results. So, is it possible that CT scans can serve as an adjunct to RT-PCR diagnosis? CT scans combine a series of images that reflect abnormal cells' metabolic activi

PET (positron emission tomography) scans help to deliver clear images of the biological functions of the body. They help to detect disease quicker compared to other imaging techniques like magnetic resonance imaging (MRI) or computed tomography (CT) scans. A PET scan is a highly technological nuclear procedure that is very safe with no known potential side effects. The risks for this procedure apply only to a few cases. The procedure requires the patient to be injected with a radioactive tracer, which is compounded with low dose radioisotope and sugar.   The radioactive compound travels to the location being imaged while the patient rests still on the scanner for about 40 to 45 minutes. Once it reaches the cancer location, the tracer will emit signals, which will be translated into images by a computer. During cancer diagnosis, doctors want to look at all angles of the disease, including the possible causes and consequences. PET can be combined with other imaging techniqu

A positron emission tomography scan is often used to help doctors diagnose, monitor, and treat several cancers, including lung, lymphomas, and head and neck cancer. They also help them find tumor locations and determine if treatment is working for patients. A PET scanner uses a radioactive tracer to show the abnormal (cancerous) cells in the body. Doctors can examine every part of a patient's body and identify cancer. Known as Fluorodeoxyglucose (FDG), the radioactive tracer is often attached to fluorine-18. When the glucose is absorbed by body cells, the fluorine-18 will break down and release gamma rays and positrons. Cancer cells are always aggressive, and they grow and multiply fast as they take in more sugar. On PET scans, cancerous cells will glow brighter. Here is why PET scans are conducted: ·          Sometimes doctors perform PET scans on neurology and cardiology patients. ·          And whenever a patient has symptoms, doctors will use a PET sca

Breast cancer is a huge problem in the health sector. Technology has not solved this problem. Annual screening and self-examination are the best methods to detect cancer early. Cancer screening has become a hot topic and is sometimes controversial, but what remains is that early diagnosis and treatment is beneficial to the patient. So why do false positives occur? This is a question many ask, especially since we live in the age of technology. This is because the technology used in screening is out of date. Mammograms pick up both benign and malignant tumors, it is up to the doctor to figure out which is which. While a PET scan is more detailed in the images it produces thus offering better clarity on whether the tumor is malignant or not. Most women start screening for breast cancer at the age 40 . Of these women, most are at the risk of developing breast cancer. These chances are increased if they are screened later on after 40. Biopsies remain the best way to tell

A ratio of the sinus scores can be calculated based on CT imaging to help predict the recurrence of chronic rhinosinusitis (CRS) with nasal polyps accurately.   According to new findings; ·          CRS with nasal polyps will always recur even after sinus surgery. The recurrence rate is at 21% within 8 years. The tissue eosinophil counts and proportions, and the presence of eosinophilicmucin have already been used as recurrence markers but the tests are often invasive or require surgery. Investigators suggest that CT scans have the potential to predict the CRS recurrence with nasal polyps. ·          The current study is investigating the importance of CT scans in predicting recurrence in CRS with nasal polyps patients who are to undergo the endoscopic functional sinus surgery. The patients already took a CT scan before surgery. ·          Two radiologists scored the scans and also assessed the maxillary sinus score (M score) as well as the total ethmoid sinus score
