Pictorial review of hematological diseases (i.e. lymphoma, plasmocytoma, multiple myeloma) and oncological pathologies (primary tumors and metastases) with PET-CT and musculoskeletal involvement as debut. Role of PET-CT in the follow up of these diseases.

The image obtained by the PET tomograph is based on capturing the emission of photons radiation resulting from the annihilation reaction of the positrons emitted by radionuclides, with the electrons of matter. The signal is captured and processed and a three-dimensional image is obtained that informs us of the distribution of the emitting radionuclide tagged tracer molecule, which is chosen to mark a specific function in the body on a biochemical level. Therefore PET provides molecular imaging of biological function. The primary attribute of PET...

We reviewed the PET-CT studies from the last 10 years in our institution with anatomopathological (confirmation) and regarding their musculoskeletal debut we divide them in SCC: spinal cord compression, bone lesion, soft tissue lesion or pathological fracture. [Fig 1] SCC: spinal cord compression SCC is a medical emergency that requires prompt diagnosis and treatment to avoid irreversible spinal cord injury. Imaging tests are essential to confirm the clinical suspicion and also, grading the severity of the disease and narrowing down the differential diagnosis. The most...

Multiple hematological and oncological diseases have a musculoskeletal debut. The PET / CT is a unique technique in the diagnosis and follow up of these diseases. Radiologists must be familiar with these imaging studies in order to better understand the management of musculoskeletal lesions.
