    Notes: Abstract To assess whether the routine use of urography (IVU) is still needed in the management of patients with renal colic and suspected ureteral calculus obstruction, we prospectively evaluated 52 patients with renal colic by a combination of colour Doppler ultrasound (CDU) and plain abdominal radiography (KUB). Forty-six patients (88.4%) were successfully treated without the need for IVU. Urography was required as a pre-lithotripsy procedure (n = 4) and to confirm non-dilated ureteral calculus obstruction uropathy (n = 2). The inean resistive index (RI) in normal subjects (n = 14) was 0.62 ± 0.06 and in obstructed kidneys (n = 37) was 0.68 ± 0.07, the difference being statistically significant (p 〈〈 0.001 ). Eight patients with functionally significant high-grade obstruction had a mean RJ of 0.69 ± 0.06, absent ureteral jet and interrenal RI difference 〉0.07. CDU and KUB provide anatomical and functional information sufficient for the management of the great majority of patients with renal colic without the use of urography.

    Infection versus neoplasm in the spine: differentiation by MRI and diagnostic pitfalls (1993)
    Springer

    Notes: Abstract MRI images of 135 patients with spine infection and 81 patients with spine neoplasm were retrospectively analysed in order to identify criteria that will help in distinguishing infection from neoplasm and in differentiating the forms of spine infection. Disc involvement occurred in 93% of infections and only 1% of neoplasms. Features of tuberculous spondylitis included paraspinal soft tissue abscesses (95%), vertebral collapse (91%), pathognomonic intraosseous abscess seen on Gd-enhanced images (84%), epidural extension (68%), gibbus (26%), skip lesions (16%) and posterior element involvement (11%). Pyogenic and brucellar infections had comparable features, i. e. predilection for the lower lumbar spine, preservation of vertebral morphology, minimal granulation tissue production and epidural extension. Primary neoplasms affected solitary vertebrate while secondary neoplasms demonstrated skip lesions and frequent extraosseous soft tissue masses. Posterior elements were frequently affected in both. MRI is a useful method for distinguishing infection from neoplasm in the spine and for differentiating tuberculous spondylitis from other infections in the majority of cases.

    Osteomyelitis: a review of currently used imaging techniques (1999)
    Springer

    Notes: Abstract. Conventional radiographs remain the initial imaging modality involved in the diagnosis of osteomyelitis. Bone scintigraphy and its specific agents did not only eliminate the problems of inherent low sensitivity of conventional radiographs, but also increased the specificity to higher degrees. Spiral CT, on the other hand, has solved several diagnostic problems, such as osteomyelitis of the sterno-clavicular junction and hidden areas in the pelvic bones. Magnetic resonance imaging with its multiplanar capability, greater anatomic details and excellent soft tissue bone marrow contrast resolution has a significant role in surgical planning and limb preservation. Ultrasound and US-guided aspiration has recently been involved in the diagnosis and management of osteomyelitis with several advantages particularly in children. Our goal in this review is to outline the ability of various imaging techniques by comparing their strengths and weaknesses in the diagnosis of osteomyelitis. Finally, we suggest various imaging algorithms for specific clinical scenarios. Spondylitis and septic arthritis are not discussed in this review.

    Rare bone infections “excluding the spine” (1999)

    Notes: Abstract. Bone infections are usually due to haematogenous spread from distant infected organs. Spread of local sepsis or contamination of open wounds are less frequent routes of infection. The commonest cause of osteomyelitis is Staphylococcus aureus. The term rare bone infections refers to diseases where only a few percent affect bone or diseases which are essentially rare; these include bacteria, fungi, parasites and non-specific conditions. Common examples are tuberculosis, salmonellosis, brucellosis, hydatidosis, madura, actinomycosis, aspergillosis and American fungal infections. Certain bone infections have become exceedingly rare, particularly atypical mycobacteria, viral embryopathies and spirochaetes. Rare bone infections are encountered in many parts of the world commonly in the tropics and in the U. S. Immunocompromise and ease of travel can lead to increased incidence. A high index of clinical suspicion is necessary for diagnosis. Specific laboratory diagnosis is not always possible. Radiographs, computed tomography, isotope studies and magnetic resonance are useful but may not make the diagnosis. Aspiration or biopsy is necessary. Rare bone infections may simulate non-infective bone lesions.
