INTRODUCTION

The main technologies for scanning soft tissue in use today are radiography, computer tomography, magnetic resonance imaging, and ultrasonography. The field continues to innovate, with new technologies emerging that promise to improve the ability of practitioners to examine and diagnose small tissue problems.

RADIOGRAPHY (X-RAY)

This is the "most common and widely available" (3) technology for diagnostic imaging. Irradiation of the body produces visual effects that help practitioners diagnosis problems: "Bones, calcifications, some tumors, and other dense matter appear white or light because they absorb the radiation. Less dense soft tissues and breaks in bone let radiation pass through, making these parts look darker on the x-ray film" (5). Radiography is a good method for examining tumors.

COMPUTER TOMOGRAPHY (CT)

This method of diagnostic imaging enhances x-rays with computer technology. The result is a "more detailed, cross-sectional image" that can help locate problems deep in the body. It is good for determining the location of a tumor in relation to its surrounding structures.

MAGNETIC RESONANCE IMAGING (MRI)

An MRI pairs "magnetic fields" with powerful computing to create high-resolution images of the body. This technology has contributed to improvements in diagnosing soft-tissue tumors.

ULTRASONOGRAPHY

This technology uses high-frequency sound waves to create an image. It is known for being convenient and non-invasive and a good method for diagnosing blood clots.

EMERGING TECHNOLOGIES

Medical device manufacturers continue to develop new technologies for diagnostic imaging. The following is a brief list of some notable developments:

1. Two-Photon Excited Flourescence Imaging (TPEF)

This method employs "near-infrared light to create . . . images" and is notable for not damaging soft tissue; it has promise for the diagnosis of coronary disease.

2. Positron Emission Tomography and Magnetic Resonance Imaging (PET-MRI)

Two technologies combine to enable oncologists to detect both metastases and anatomical detail.

3. Cone Beam CT

Dentists use this technology to prepare three-dimensional images. The patient's exposure to radiation is low compared to traditional x-rays.

4. Lasers and Other Advanced Imaging Devices

The dental field is seeing a variety of new diagnostic devices emerge in the marketplace. These include Canary (a pulsing red light that shines on teeth to reveal cavities), S-Ray (an ultrasonic mapping device), Lasers (for diagnosis and treatment of gum disease), and VELscope (blue light that helps identify changes in tissues).

CONCLUSION

Medical practitioners have a range of tools for examining and diagnosing soft tissue disorders. The number of resources is increasing as new technologies emerge.
