USE OF ULTRASOUND AND MRI TECHNIQUES-LESSON 134

-

Ultrasound: High-frequency impossible to hear muffled sound waves are sent and these waves are bounced off by body tissues. The movement of sound waves are recorded to give the information about the structure of the inside organs. The good transmission of waves is ensured by placing an instrument near the skin and by smother the skin surface by an oily substance. Oil substance probably a mineral oil is put for the diffusion of sound waves properly.
The ultrasound instrument produces dumpy sound waves in cyclic beats. Each wave is in different speed of motion and invades through the tissues inside the body and becomes aware of boundaries amid tissues of diverse compactness. These waves are passed back to the ultrasound monitor and recorded. This record is called echogram or sonogram.
This instrument is used not only by radiologists, but also by ophthalmologists to detect intracranial and ophthalmic lesions. Cardiologists also use this instrument to identify blood valve and heart valve ailments. This is called echocardiogram.
Gastroenterologists use this equipment to track down of any abdominal masses in the GI tract.
Gynecologists and obstetricians use this equipment to make a distinction between whether there is a single child or more than one in the uterus.
Obstetricians perform amniocentesis to track down tumors or cysts if any in the uterus. Measurement of fetal size and age of the fetus can also be calculated using ultrasound wave technique.
ADVANTEAGES OF THE ULTRASOUND:
Comparing iodine contrast study and other studies ultrasound is very safe and has side effects as the sound waves used in this method are nonionizing. Passing these waves inside the body will not damage the internal organs or any tissues.

They are as follows: Hypochondriac, epigastric, lumbar, umbilical, inguinal, and hypogastric. Now we will see about all abdominopelvic quadrants and regions one by one now. 1. Hypochondriac regions (2): The two upper right and left regions below the cartilage (chondr/o) of the ribs that extend over the abdomen. 2. Epigastric regions (2): This is the region above the stomach. 3. Lumbar regions (2): The two right and left regions near the waist part of the body. 4. Umbilical regions (1): The region of the umbilicus or navel portion of the body. 5. Inguinal regions (2): The two lower right and left regions of the body, inguin/o means groin that is the area where the two legs join together with the trunk of the body. This region is also called iliac regions because they are near the ilium part

Body cells are different types. We often may read about stem cell types. Like in a movie there are many actors to do their different roles to establish a story, in our body there are different kinds of cells to do different roles to keep the body stable and active. The cells in our body are of two types: 1. Somatic cells. Our body contains Muscle cells, Nerve cells, Skin cells, and Fat cells. These kind of cells performing mainly body related functions and so they are called Somatic cells. There are varieties of cells inside the body. Every cell is different or specially created to do their special role inside the body throughout. Fat Cell: For example in body cells a FAT CELL has in it empty and large spaces for fat storage, and a muscle is slender and long and has in it fiber material that help in relaxing and contracting, as well as a skin cell is square in shape and also flat in structure to give protection to our body and a nerve cell which is long in struct
