 PET-CT (Positron Emission Tomography-Computed Tomography) | explained


PET-CT (Positron Emission Tomography-Computed Tomography) is a hybrid imaging modality that combines two diagnostic techniques: Positron Emission Tomography (PET) and Computed Tomography (CT). In a PET scan, a radioactive tracer is injected into the patient and produces gamma rays that are detected by the PET camera, which creates images of metabolic activity in the body. In a CT scan, X-rays are used to create detailed images of anatomy. The PET-CT combines these two techniques to provide both functional and anatomical information in a single scan. It is used in medical diagnosis for conditions such as cancer, heart disease, and neurological disorders.

what is biosensor?

 What is biosensor? A biosensor is a device that uses a biological component (such as enzymes, antibodies, or DNA) to detect and measure specific molecules or compounds in a sample. Biosensors have a wide range of applications in medicine, environmental monitoring, and industrial processes, among others. One of the most common types of biosensors is the enzyme-based biosensor. These biosensors use enzymes as the biological component to detect and measure specific molecules in a sample. For example, glucose biosensors use enzymes that specifically catalyze the oxidation of glucose, and the resulting electrical signal can be used to measure the glucose concentration in a sample. Enzyme-based biosensors are commonly used in medical applications, such as monitoring glucose levels in people with diabetes. Another type of biosensor is the antibody-based biosensor. These biosensors use antibodies as the biological component to detect and measure specific molecules in a sample. Antibodies can

 What is electrocardiography? how to diagnose?  Electrocardiography (ECG or EKG) is a diagnostic test that records the electrical activity of the heart. The test is used to evaluate the heart's electrical activity and rhythm, and to diagnose and evaluate conditions such as heart attacks, arrhythmias, and heart disease. ECG test is performed by attaching electrodes to the skin of the chest, arms, and legs. The electrodes are connected to an ECG machine, which records the electrical activity of the heart. The test is usually done while the patient is lying down, and it takes about 5-10 minutes to complete. The ECG tracing, which is a graph of the heart's electrical activity, is analyzed by a healthcare professional. The tracing shows the electrical activity of the heart as it goes through its normal cycle of contraction and relaxation. The healthcare professional can use this information to diagnose and evaluate conditions such as: Heart attacks: A heart attack occurs when the bl

how to prepare CuBTC?

  how to prepare CuBTC? Copper (II) benzene-1,3,5-tricarboxylate (CuBTC) can be prepared through a synthetic process, typically involving the following steps: Preparation of starting materials: The starting materials needed to prepare CuBTC include copper (II) acetate, benzene-1,3,5-tricarboxylic acid (H3BTC), and a solvent such as water or ethanol. Mixing of starting materials: The starting materials are mixed together in a flask or reaction vessel and heated to a temperature of around 80 to 100°C. The reaction is typically carried out under stirring and/or reflux conditions. Formation of the product: During the reaction, the copper (II) acetate reacts with the H3BTC to form the product, CuBTC, and a byproduct, such as acetic acid. Isolation and purification of the product: The reaction mixture is then cooled and the product is isolated and purified through techniques such as filtration, recrystallization, or column chromatography. Characterization of the product: The purified product
