According to Lee, Sadigh, Mankad, Kapse, & Rajeswaran (2016), “osteomyelitis is inflammation of the bone marrow secondary to infection, which can progress to osteonecrosis, bone destruction, and septic arthritis.” Osteomyelitis is described as an inflammation of bone almost often because of a typical bacterial infection. Additionally, other non-pyogenic causes of osteomyelitis are skeletal syphilis, tuberculous osteomyelitis, and fungal osteomyelitis. This condition does not discriminate by gender and can occur at any age. However, for individuals who have no specific risk factors, osteomyelitis is predominantly common among those aged 2-12 years. Additionally, this condition is more common among males and the ratio of male to female is 3:1.
Diagnosis report shows that osteomyelitis is more common in the lower limb, then vertebrae, radial styloid, and least common around the sacroiliac joint. Additionally, the osteomyelitis location within the human bone varies significantly with age because of the changing blood supply. Thus, neonates experience this condition around the metaphysis and/or epiphysis regions, children around the metaphysic region, and regions of subchondral and epiphyses for the adults. All in all, this condition can be diagnosed using nuclear medicine study and CT scan. Thus, this paper will discuss how CT and nuclear medicine diagnose osteomyelitis.
Nuclear medicine specialty involves giving the patient a radioactive medication in small amounts, known as a radiopharmaceutical. The radiopharmaceutical is a radioactive material that is administered internally, through inhalation, injection, or swallowing (Cain, 2017). On the other hand, CT Scanning or Computed Tomography is an advanced technology system which is used to study the inner functioning of the body. CT helps the physician "see" the inner parts of the body (anatomy). While nuclear medicine is used to visualize organs or tissues, it can also be used for whole-body visualization just like the CT scanning if an agent that targets specific cellular functions or receptors is used. Some of the examples of the techniques that include whole-body visualizing are PET/CT scan, octreotide scans, MIBG scan, gallium scan, as well as indium white blood cell (WBC) scan.
First, in the diagnosis and treatment of osteomyelitis, CT scanning is superior to other techniques such as plain film and MRI because it depicts the bony margins and identifies an involucrum or sequestrum. CT scans show the detailed images of body parts such as organs, bones, fat as well as muscles. These scans provide greater details and clarity of “inner” organs, bone, soft tissue as well as blood vessels which cannot be achieved using a regular X-ray (Osteomyelitis, 2015). However, features of a CT scan are similar to those from plain films. Nonetheless, CT minimizes the exposure to radiation.
With computed tomography, a dye is swallowed or injected into a patient's vein to ensure the organs or tissues are more clearly. In CT, a large donut-like X-ray machine known as a CT scanner is used takes X-ray pictures from various angles of the human body. This scanner produces an extremely narrow “pencil” X-ray beam which is moved in a circle to allow the doctor or physician to obtain many different views and pictures of the same structure or organ (Jeffcoate, 2017). It is typically a different X-ray study as it coalesces several X-ray pictures with the help of a computer to produce cross-sectional views of body structures and internal organs, and if need be, three-dimensional images.
The pictures are processed to give cross-sectional images of the patient's body. From all the images, the body appears as the body's X-ray "slice" record on a video. The image produced is known as a tomogra
