Radiology diagnostics and electrical testing

ElectrocardiogramPicture representing electrical activity of heart
electro- electricitycardio- heart-gram picture or record
ElectroencephalogramPicture showing brain wave activity
electro- electricityencephalo- brain-gram picture or record

Dr. Rob explains · The brain is able to process information because of electrical activity in our body. Using an electroencephalogram is a simple and effective way to measure a person's brain wave activity to detect abnormalities such as seizures. Detectors called leads are placed on the head either using a hat or stuck individually. Brain wave electricity is measured and sent to a display for analysis.

MRIMagnetic resonance imaging

Dr. Rob explains · A diagnostic test called Magnetic Resonance Imaging - also referred to using its initials MRI – is an extremely accurate tool for determining a great variety of medical conditions involving tissue damage throughout the body. When placed inside of the MRI machine as shown, the diagnostic test will take a series of images that display different segments of the body in progression. As shown here, these images are from an MRI of a patient’s head. Each picture is a bit different as each image is displayed from a different portion of the computerized scan. Although an MRI works in a very interesting manner, the procedure is completely non-invasive and the patient will not feel any of the process that is happening.

Dr. Rob explains · Although x-ray pictures were discovered in 1895, their clarity and advancement over the years has been astonishing. Many times, an x-ray picture, or radiogram, will be a first diagnostic test for a condition. Bone injuries, pneumonia, as well as many other conditions can be determined by a simple non-invasive x-ray.

SonogramImage created by computerized reflected sound waves
sono- sound-gram picture or record

Dr. Rob explains · Shown here are some examples of fetal images taken through the mother’s abdominal wall and into the womb using sonography. Advancements in ultrasound technology have been tremendous over the last few decades. A 2D image of a fetus as shown in the top left may be extremely helpful and accurate. However, the images gained from the more advanced 3D images and even 4D video that can be utilized today amaze both soon-to-be parents as well as the medical community when they are viewed.

TomogramPicture made by an x-ray that produces slice images (CT scan)
tomo- in slices-gram picture or record

Dr. Rob explains · Computerized tomography, also referred to as a CT scan, is a specialized x-ray technology that allows physicians to see detailed views of tissues inside of the body. By taking pictures as a series of sliced images, a doctor can diagnose problems with precise accuracy. CT scans can detect such issues as brain trauma from concussions or strokes, tumors, and many other tissue damage throughout the body.

Centesis Procedures: Pulling fluid from locations for diagnostic testing

AbdominocentesisSurgical puncture to remove fluid in the abdomen
abdomino- abdomen-centesis surgically puncture to remove fluid

Dr. Rob explains · is a treatment option for trauma as well as cancer patients who have a fluid build up within the body cavity. This fluid build up can lead to a condition called ascites where an accumulation of fluid in the peritoneal cavity causes abdominal swelling. Ascites can also be caused by high blood pressure in vessels to major abdominal organs. An abdominocentesis removes this excess fluid.

AmniocentesisSurgical puncture to remove amniotic fluid from the womb
amnio- amniotic sac in the womb-centesis surgically puncture to remove fluid

Dr. Rob explains · Testing a mother's blood to detect fetal complications is a simple, non-invasive and effective process. However, if those blood tests indicate that there may be issues with the baby, then an amniocentesis procedure can be performed to give more specific results. Using an ultrasound procedure as a guide, a needle is inserted into the womb. Carefully, a small sample of only amniotic fluid is drawn and tested. Amniotic fluid in the womb that surrounds a baby contains fetal cells that are able to be analyzed. This test is completely at the mother’s discretion and is optional. However, it is typically offered to pregnant women age 35 and older due to the increased risks associated with pregnancies in older mothers.

Centesis Procedures: Pulling fluid from locations for diagnostic testing continued

PericardiocentesisSurgical puncture to remove fluid from around the heart
peri- aroundcardio- heart-centesis surgically puncture to remove fluid

Dr. Rob explains · In some cases, excess fluid builds up between the two layers of the pericardium, a membrane that reduces friction around the heart. In order to keep the heart functioning normally, physicians can insert a needle or catheter into the pericardial sac to remove the excess fluid.

ThoracentesisSurgical puncture to remove fluid from chest cavity
thorac- chest cavity-centesis surgically puncture to remove fluid

Dr. Rob explains · In various conditions, excess fluid builds up in the space around the lungs called the pleura. This makes breathing difficult because the lungs cannot inflate fully. A procedure called a thoracentesis draws fluid out of that space to allow for better breathing. Also, the fluid can be tested if the cause of the disorder is unknown.
