Comparative Study
MRI of paraspinal muscles in lumbar degenerative kyphosis patients and control patients with chronic low back pain.
To compare lumbar musculature in lumbar degenerative kyphosis (LDK) patients and chronic low-back pain (CLBP) patients. ⋯ Evaluation of paraspinal musculature should be considered when assessing MRI images of the lumbar spine. Measurement of the CSA, visual grading of fatty atrophy and the assessment of the fascia may help physician and radiologist reach a more confident diagnosis for the patients with clinically suspicious LDK.

The objective of this study was to determine whether dopamine transporter (DAT) scintigraphy influences the management of movement disorders in clinically indeterminate cases. ⋯ This series illustrates the value of DAT scintigraphy in the management of clinically indeterminate movement disorders at a tertiary referral centre arguing for its use in the initial diagnostic process. However, it is clear that the use of DAT scintigraphy poses significant resource implications. Further evidence should clarify the exact role of DAT scintigraphy in clinically indeterminate cases.

To evaluate frequency and clinical relevance of the 'small bowel faeces' sign (SBFS) on computed tomography (CT) in patients with and without small bowel obstruction (SBO) presenting with acute abdominal or acute abdominal and flank pain. ⋯ A SBFS is more frequent in patients presenting with acute abdominal/flank pain without bowel obstruction. When seen in association with moderate or severe small bowel dilatation, a SBFS is significantly more common in patients with SBO. When a SBFS is associated with normal or mildly dilated small bowel, the majority of patients have no bowel obstruction.

Proton magnetic resonance spectroscopy (1H MRS) non-invasively provides information on the biochemical profile (typically including up to nine metabolites and mobile lipids) of brain tissue, which varies according to the underlying disease process. A number of studies have assessed its accuracy in the diagnosis of adult brain tumours. This article describes the basic principles of 1H MRS, the metabolic profiles of different brain tumours, and practical points to aid interpretation of spectra. The literature is reviewed regarding the role of 1H MRS in the diagnosis of brain tumours and more specifically where it has proven to be of additional benefit over conventional magnetic resonance imaging.

To evaluate the relationship between the severity of bronchiectatic diseases, as evident on high-resolution computed tomography (HRCT) and the patient's quality of life measured using the St George's Respiratory Questionnaire (SGRQ). ⋯ A correlation between the severity of bronchiectatic disease as expressed in HRCT and the health-related quality of life exists in patients with a more severe bronchiectatic disease but not in patients with mild disease. Such correlation depends on the location of the bronchiectasis in the pulmonary tree.
