A very common use is the diagnosis of multiple myeloma, where tumour deposits appear as "punched-out" lesions. The standard set of X-rays for a skeletal survey includes X-rays of the skull, entire spine, pelvis, ribs, both humeri and femora (proximal long bones). It is more effective than isotope scans at detecting bone involvement in multiple ...
The diagnostic examination of a person with suspected multiple myeloma typically includes a skeletal survey. This is a series of X-rays of the skull, axial skeleton , and proximal long bones. Myeloma activity sometimes appears as "lytic lesions" (with local disappearance of normal bone due to resorption) or as "punched-out lesions" on the skull ...
Osteolytic lesion at the bottom of the radius, diagnosed by a darker section that indicates a loss of bone density. An osteolytic lesion (from the Greek words for "bone" (ὀστέον), and "to unbind" (λύειν)) is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer and multiple myeloma.
Most cases of SPB progress to multiple myeloma within 2–4 years of diagnosis, but the overall median survival for SPB is 7–12 years. 30–50% of extramedullary plasmacytoma cases progress to multiple myeloma with a median time of 1.5–2.5 years. 15–45% of SPB and 50–65% of extramedullary plasmacytoma are disease free after 10 years.

Bone scan showing multiple bone metastases from prostate cancer. Some of the earliest investigations into skeletal metabolism were carried out by George de Hevesy in the 1930s, using phosphorus-32 and by Charles Pecher in the 1940s. [6] [7] In the 1950s and 1960s calcium-45 was investigated, but as a beta emitter proved difficult to image.
A skeletal survey can help distinguish between Waldenström macroglobulinemia and multiple myeloma. [50] Anemia occurs in about 80% of patients with Waldenström macroglobulinemia. A low white blood cell count and low platelet count in the blood may be observed.
Multiple myeloma is a hematologic cancer, originating in the bone marrow, which also frequently presents as one or more bone lesions. [10] Germ cell tumors, including teratoma, often present and originate in the midline of the sacrum, coccyx, or both. These sacrococcygeal teratomas are often relatively amenable to treatment. [11]
Plain X-ray of the wrist and hand. In the clinical context, "invisible light" medical imaging is generally equated to radiology or "clinical imaging". "Visible light" medical imaging involves digital video or still pictures that can be seen without special equipment. Dermatology and wound care are two modalities that use visible light imagery.
