Digital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.
These are special x-rays of the lower face, teeth and jaws. An OPG provides a panoramic view of the mouth, teeth and bones of the upper and lower jaws. The Lat Ceph results in a lateral or sideways view of the face.
Diagnostic medical sonographers use sound waves to generate images used for assessing and diagnosing various medical conditions. Many people associate sonography with pregnancy. It's how a fetus can be seen in the womb. But this technology has many other applications in the diagnosis and treatment of medical conditions in the abdomen, breast, heart and blood vessels and, more recently, in diagnosing and treating musculoskeletal problems.
At least 300 radiologists and obstetricians across the country are being trained at an international conference in 5D ultrasound technology which provides an in-depth understanding of the foetus' movements, its medical parameters and diagnosis. While this is done as early as in the 12th week of pregnancy, scans in the later periods of pregnancy - when the foetus' features are more clear and the baby's characteristics, better defined - the parents-to-be can also enjoy seeing their yet-to-be-born child yawn, suck its thumb, kick out, twitch or make faces while still inside the mother's womb.
Fetal echocardiography is a test similar to an ultrasound. This exam allows your doctor to better see the structure and function of your unborn child’s heart. It’s typically done in the second trimester, between weeks 18 to 24. Not all pregnant women need a fetal echocardiogram. For most women, a basic ultrasound will show that all four chambers of their baby’s heart have developed.Your obstetrician may recommend that you have this procedure done if previous tests detected an abnormal heartbeat in the fetus.
The nuchal translucency scan (also called the NT scan) uses ultrasound to assess your developing baby's risk of having Down syndrome (DS) and some other chromosomal abnormalities, as well as major congenital heart problems. The NT scan measures the clear (translucent) space in the tissue at the back of your baby's neck. Babies with abnormalities tend to accumulate more fluid at the back of their neck during the first trimester, causing this clear space to be larger than average. The NT scan is not invasive.
Color Doppler sonography has become an integral part of cardiovascular imaging. Significant improvements have recently occurred, improving the visualization and evaluation of intra-organ vascularity, resulting from enhancements in delineation of tissue detail through electronic compounding and harmonics, as well as enhancements in signal processing of frequency- and/or amplitude-based color Doppler sonography.
The Soft tissue ultrasonography (USG) findings that might suggest benignancy of a soft tissue mass are a small size, superficial location, homogeneous echo pattern, and hypovascularity. However, these findings are not sufficiently reliable to definitively characterize the nature of a lesion. US findings can be misleading, since similar findings also occur in synovial sarcoma, liposarcoma, melanoma, lymphoma, myeloid sarcoma, and small metastasis.
The thyroid gland lies in the neck, in front of the upper part of the trachea. Thyroid hormones regulate the basal metabolic rate and are important in the regulation of growth of tissues, particularly nervous tissue. The second type of hormone produced from the thyroid gland is calcitonin, which regulates blood calcium levels along with parathyroid hormone and acts to reduce blood calcium by inhibiting its removal from bone.
