Investigations of the skeleton and the joints

SPECT/CT and bone scintigraphy with or without perfusion

Preparation
None. It is not necessary to be fasting.

Process
The examination takes place in 2 sessions

1st session
Intravenous injection and possibly acquisition of an early imaging (duration: 15 – 30 min).
2nd session
Acquisition of late imaging (total duration 1 hr).

Between the two sessions (3-4 hr), you are free to leave the institute. It is recommended that you generally hydrate well and drink about ½ litre of water. During the examination under the camera please remain motionless.

Main clinical indications

  • Search for prostate and breast cancer bone metastases
  • Search for primary bone tumour
  • Investigation of rheumatologic or orthopaedic pathology
  • Search for algodystrophy

Principle
The imaging is based on the uptake of a radiopharmaceutical by the bone matrix. The bone responds to a local aggression, of a benign, malignant, traumatic or other nature, by a repairing process, that is to say, an acceleration of the formation of the bone by specialized cells (osteoblasts). The scintigraphy, which allows the entire skeleton to be analysed, will reveal with great sensitivity the majority of the bone lesions, visualized in the form of increased activity.

Bone metastases of prostate cancer

Osteoarticular lesion (ankle)

Stress fracture (foot)

Trigone conflict (supernumerary bone)
