Which Imaging Technique is Best for Diagnosis and Why?

To date, ultrasound is the first-line imaging technique and the only one validated to aid in the diagnosis, staging, evaluation of activity, orientation of percutaneous and surgical procedures, as well as the monitoring of the treatment of HS. X-rays are probably the most common type of medical imaging technique that exists. They are often the most preliminary diagnostic tool used for various injuries, diseases and conditions, and are used to detect all types of problems, from fractures to disease progression and treatment effectiveness. It is a versatile and very effective tool.

CT scans are also cross-sectional images that show greater body vision and help identify problems. Often, CT scans are a follow-up to X-rays that show strange findings. They provide a detailed view of various organs, including size, shape, dimensions, abnormalities and growths. Ultrasounds are another very common diagnostic imaging technique, in which high-frequency sound waves are used to look more closely at soft tissues, such as organs.

Because they are generally safer than X-rays and CT scans and do not require radiation, they are also used for pregnant women. Imaging plays an important role in modern medicine. Modern diagnostic imaging techniques, such as x-rays, ultrasounds, CT scans and magnetic resonance imaging (MRI), can show the internal structures of the body in great detail. In addition to contributing to diagnosis, imaging plays an important role in the staging of soft tissue malignancies and, potentially, in evaluating the response.

However, image quality has improved significantly thanks to the introduction of multi-detector scanners and high-quality multi-plane reformatted images, providing faster scan times, reducing motion artifacts and allowing higher volumes of coverage. Imaging evaluation of a suspicious soft tissue mass begins with a conventional X-ray, particularly of the extremities and other surface masses. MRIs are another common type of diagnostic imaging technique and are generally used to obtain a complete cross-sectional image of the body's soft tissues and bones using magnetic rays and photographic technology. Soft-tissue tumor imaging requires a multimodal approach, without any single imaging modality being ideal for all tumors.

This growing variety of image types offers health professionals many options for showing what's happening inside the body. Fully funded by the Victorian government, this website provides medical and health information on images and related health conditions and injuries, of guaranteed and reliable quality, up-to-date, locally relevant and easy to understand. Below are different types of images with explanations of how they are used and some advantages and disadvantages of each one. However, controversy persists and, in another study conducted by Mirowitz et al., they showed no advantage in the use of dynamic imaging due to the significant overlap in the rate of increase of benign and malignant soft tissue tumors.

X-rays use electromagnetic radiation to create images that show bones or other dense structures inside the body. Ultrasound uses high-frequency sound waves to produce moving images on a screen of the inside of the body, including organs, soft tissue, bones, and the fetus. CT scans use X-rays to create detailed cross-sectional images of organs or other structures inside the body. MRI uses magnetic fields and radio waves to show detailed images of organs, soft tissue, bones, ligaments and cartilage.

Public information resource for patients about diagnostic imaging (radiology) tests developed by doctors from the Radiological Society of North America (RSNA) and the American College of Radiology (ACR) is also available.
