CT Scan is CT imaging in conjunction with computing algorithms to image the body. A CT scan uses a computer that takes data from several X-Ray images of structures inside a human’s or animal’s body and converts them into pictures on a monitor. In CT ,an X-Ray generating tube which is opposite to X-Ray detector in a ring shaped apparatus rotate around a patient producing a computer generated cross-sectional images. CT scan is required in the axial plane, while coronal and Sagittal images can be rendered by computer reconstruction. Radio contrast agents are often used in CT scan for enhanced delineation of Anatomy. Although radiographs provide higher spatial resolution, CT can detect more sensitive attenuated lesion on the X-Rays in short durations.

Radiology is a medical area of expertise that make use of the of imaging to both diagnosis and treatment of the disease, visualized within the human body in order to evaluate the physiological functions and anatomical configuration of the body.
The Radiologist uses various imaging technologies to diagnose and treat different diseases; the commonly used techniques are as follows:-
- X-Ray Radiography
- Computed Tomography (CT)
- Nuclear Medicine
- Positron emission tomography (PET)
- Magnetic Resonance Imaging (MRI)
In Interventional Radiology minimum invasive procedure are applied. The medical imaging is usually carried out by radiographers or radiologic technologists. A radiologist interprets or reads the images and produces a report of finding and impression or diagnosis. This report is then transmitted to the ordering physician either routinely or emergently. Initially, the radiographer was known as roentgenogram, while skia grapher (from ancient Greek words for “shadows and writer”) term was used until about 1918 which mean radiographer.

Mother should not eat certain soft cheeses such as feta, Brie, Camembert, blue-veined, and Mexican-style cheese in pregnancy because of a risk of becoming infected.

What is Pregnancy
Pregnancy is defined as fertilization of sperm with a ova in women uterus results in development one or more offspring when fertilized eggs covers a period of eight weeks ,it is term as embryo and above eight weeks it is term as foetus. Normal child birth occurs about 38 weeks after conception. Human pregnancy is divided into three trimesters. In first trimester risks of miscarriage are more. In the second trimester fetal development can easily monitored and diagnosed. The third trimester the fetus has the ability to survive with or without medical help outside the uterus.
Process of Pregnancy
Pregnancy begins with implantation of fertilized egg in the uterus. The fertilized egg completely differentiate into cell, forms the embryo. The outline of the body organs and the nervous system developed in eight week of embryonic stage ,placenta and umbilical cord develop from embryonic stage to support the organs. Sex organ appear during the third month of pregnancy. The fetus grow in both weight and length ,maximum growth of fetus takes place in the last week of pregnancy. Pregnancy is considered at term, when gestation has completed 37 weeks. Continue reading “Being Pregnant or Pregnancy”
People usually “eat to live”; by selecting proper diet, one can now “eat to live longer”. Here are few foods that can help you to live longer and healthier life. people who eat slowly generally lives longer:-
Fish is a highly nutritious food and an excellent protein food with fewer calories. It is rich in omega 3 fatty acids; the omega-3 fatty acids in fish are good for your heart and strengthen the immune system. Fish is a perfect food, particularly in terms of protein, vitamin D and trace elements. Eating Fish regularly is likely to enhance your life span.
Fruits and vegetables are full of vitamins, fiber and other essential nutrients, eating more than five fruits and vegetables a day is healthier. Fruits and vegetables also contain carbohydrates that can amply meet the body’s energy needs. Diets rich in vegetables and fruits Lowers blood pressure, reduces the risk of heart disease, stroke, and probably some cancers. It lowers the risk of eye diseases, digestive problems and mellows the effects on blood sugar that can help keep appetite in check. Orange, broccoli and spinach are full of antioxidants and are recommended in diet. Include dark leafy greens, tomatoes, and anything that has a rich yellow, orange, or red color.

Yoga Cat Pose or Marjariasana
In Yoga Cat Pose, the alignment of your center depends on the positioning of your pelvis. Therefore, think of your hip positioning as the center of each pose. In this pose, your spine is the most significant line of energy as in every other pose. Continue reading “Yoga – Cat Pose or Marjariasana”
What is Angina or Angina Pectoris
Angina or Angina Pectoris (Latin word means ‘squeezing of the chest’) is chest pain caused by insufficient blood flow and oxygen to the heart muscle. This is frequently caused by narrowing or blockages of the coronary arteries that deliver oxygen-rich blood to the heart muscle, known as coronary artery disease. The heart muscle is overhauled by the coronary arteries, if these arteries are narrowed; the decreased blood flow implies that the heart muscle receives less oxygen than it needs to properly function. The cells of the heart, called Myocardial Cells, are damaged. The severity of the heart attack depends on how many Myocardial Cells are damaged or killed. Angina is often a warning sign of an impending heart attack, one patient in ten is likely to have a heart attack within a year of diagnosis of Angina.

Transfusions are used to keep your number of blood cells at a safe level. They may be used before, during or after other treatments. Patients may receive whole blood or just specific components of the blood needed to treat their particular condition. To avoid a transfusion reaction, donated blood must be compatible with the blood of the patient who is receiving the transfusion. Before a blood transfusion, two blood tests “type and cross match” are done. Cross Match chart is shown for ready reference.
Components of Blood
Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in plasma (~55% of volume).
Red cells, or erythrocytes, carry oxygen from the lungs to your body’s tissue and take carbon dioxide back to your lungs to be exhaled. Continue reading “Blood Matching for Blood Transfusion”
Amalgamation of blood from two human beings can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions resulting in fatal consequences. In 1901, Austrian Karl Landsteiner discovered human blood groups that made the blood transfusions safe, previously the transfer of blood or blood components into a person’s blood stream resulted in many deaths.
Quantity of Blood in Human Body
Blood transports oxygen to various parts of the body. An adult human has about 4–6 liters of blood circulating in the body.
What are Antigens?
Antigen is a substance, usually a protein, on the surface of a cell or bacterium that stimulates the production of an antibody.
What are Antibodies?
A protein produced by B cells in the body in response to the presence of an antigen, e.g. a bacterium or virus. Antibodies are a primary form of immune response in resistance to disease and act by attaching itself to a foreign antigen and weakening or destroying it.
The most recognized and medically significant blood types are in the ABO group. There are four principal types having two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual’s type in most cases.
