“…However, mri is a superior imaging method for dogs with early diskospondylitis (Kraft and others 1998). The mri changes in the dog in this study revealed disc space, and vertebral body and perivertebral soft tissue signal alterations, which are virtually pathognomonic for diskospondylitis in human beings (Hovi and others 1994). In contrast, mri signal alterations associated with canine lumbosacral stenosis include disc protrusion and vertebral canal or nerve root impingement by bony or soft tissue structures (De Haan and others 1993, Adams and others 1994).…”

The clinical management of patients with skeletal metastases puts new demands on imaging. The radiological imaging in screening for skeletal metastases entails detection, metastatic site description and radiologically guided biopsy for morphological typing and diagnosis. Regarding sensitivity and the ease in performing surveys of the whole skeleton, radionuclide bone scintigraphy still is the first choice in routine follow-up of asymptomatic patients with metastatic disease of the skeleton. A negative scan has to be re-evaluated with other findings, with emphasis on the possibility of a false-negative result. Screening for metastases in patients with local symptoms or pain is best accomplished by a combination of radiography and MRI. Water-weighted sequences are superior in sensitivity and in detection of metastases. Standard spin-echo sequences on the other hand are superior in metastatic site description and in detection of intraspinal metastases. MRI is helpful in differentiating between malignant disease, infection, benign vertebral collapse, insufficiency fracture after radiation therapy, degenerative vertebral disease and benign skeletal lesions. About 30% of patients with known cancer have benign causes of radiographic abnormalities. Most of these are related to degenerative diseases and are often easily diagnosed. However, due to overlap in MRI characteristics, bone biopsy sometimes is essential for differentiating between malignant and nonmalignant lesions. Performing bone biopsy and aspiration cytology by radiologist and cytologist in co-operation has proven highly accurate in diagnosing bone lesions. The procedure involves low risk to the patient and provides a morphological diagnosis. Once a suspected metastatic lesion is detected, irrespective of modality, the morphological diagnosis determines the appropriate work-up imaging with respect to the therapy alternatives. The integration of multimodality imaging in the assessment of skeletal metastases is complex and requires multidiciplinary co-operation in order to optimize screening and medical clinical care with respect to the prognosis and life quality of patients with bone metastatic disease.
