On physical exam, a doctor will look for tenderness along the affected tendon and pain when the muscle to which the tendon is attached is used against resistance. There are specific tests for specific tendons. The tendon can be inflamed and the ov...

Some tendon injuries are superficial and easy to identify. These include "tennis elbow" (extensor tendinitis) over the outside of the elbow, and Achilles' tendinitis just above the heel of the foot. There are several tendons in the shoulder that c...

X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, x-rays are emitted by a machine as individual "particles" (photons) that pass through the body and then get detected by a sensitive film. Structures that are dense (such as bone) will block most of the photons, and will appear white on developed film. Structures containing air will be black on film, and muscle, fat, and fluid will appear as shades of gray. Metal and contrast media (intravenous or oral contrast) blocks almost all the photons and will appear bright white. The basic science of x-ray generation and detection is the key behind general radiographs of the body, mammography, fluoroscopy (real-time imaging on video screens), and computed tomography (CT).

X rays are a type of radiation used in imaging andtherapy that uses short wavelength energy beams capable of penetrating most substances except heavy metals. Purpose Diagnostic x rays are some of the most powerful medical imaging tools available.

|
X rays are electromagnetic radiation that differentially penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. These images are called diagnostic x rays.

 |
Body positions in x-ray exams are based on body part, suspected defect or disease, and condition of the patient. The radiographer, also known as the x-ray tech or more formally as the radiologic technologist, uses standardized body positions in performing an x-ray exam.

MRI is a non-invasive procedure that uses powerful magnets and radio waves to construct pictures of the body. Unlike conventional radiography and computed tomographic ( CT ) imaging, which make use of potentially harmful radiation ( x-rays ), MRI imaging is based on the magnetic properties of atoms. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the natural background magnetism from the earth. A very small percentage of hydrogen atoms within a human body will align with this field. When focused radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, they will return a signal. The subtle differences in that signal from various body tissues enables MRI to differentiate organs, and potentially contrast benign and malignant tissue. Any imaging plane (or slice) can be projected, stored in a computer, or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in the area of interest can cause significant errors, called artifacts, in the reconstructed images.

Cardiac nuclear imaging is also called a “perfusion scan.” A radioactive tracer is delivered into the bloodstream. Then a camera scans the tracer in the blood as it flows through the heart muscle.

Magnetic resonance imaging (MRI) is a diagnostic imaging procedure that uses radio waves, a magnetic field, and a computer to generate images of the anatomy. Purpose MRI is used to visualize the body to assist doctors in their efforts to diagnose certain diseases or conditions and to evaluate injuries.

Magnetic resonance imaging (MRI) is one of the newest diagnostic medical imaging technologies that uses strong magnets and pulses of radio waves to manipulate the natural magnetic properties in the body to generate a visible image. In the field of mental health, an MRI scan may be used when a patient seeks medical help for symptoms that could possibly be caused by a brain tumor.

Magnetic resonance imaging (MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images.
