PURPOSE: Computed tomography (CT)-guided periradicular infiltration has become an accepted procedure for treating radiculopathy-associated low back pain. The purpose of this study is to compare spot scanning and segmental helical planning CT in terms of dose reduction. MATERIALS AND METHODS: Eighty-five patients underwent CT-guided single-site lumbar periradicular therapy. Prior imaging was not available for planning. Sixty-three patients were examined with a new dedicated spot scanning technique (group I), and twenty-two patients underwent conventional segmental planning CT examinations with helical image acquisition serving as controls (group II)...

Xanthogranulomatous pyelonephritis (XGP) is a rare form of pyelonephritis associated with repeated infection, chronic inflammation, and obstruction. Various fistulas, including those to the intestine, are a known association with XGP. Here, a 55-year-old woman with a history of multiple previous renal calculi presented with dysuria and back pain. Contrast-enhanced computed tomography (CT) revealed a soft tissue density in her renal pelvis and perirenal space consistent with XGP along with a tract connecting the upper pole of her right kidney to the second portion of the duodenum...

INTRODUCTION: By using a combination of magnetic resonance imaging (MRI) and computed tomography (CT) of the lumbar spine, it is possible to distinguish between spinal stenosis caused by bone compression and specific soft tissue epidural intraspinal lesions that cause localized spinal canal stenosis and neural compression. Examples include facet cysts and yellow ligament hypertrophy. Many of these patients are elderly with medical comorbidities that make open surgery problematic. MATERIALS & METHODS: This is a study of patients with predominantly soft tissue stenosis being treated with targeted intraspinal radiofrequency (RF) heat ablation...

OBJECTIVE: A test-retest cohort study was conducted to assess the use of a novel computer-aided, combined movement examination (CME) to measure change in low back movement after pain management intervention in 17 cases of lumbar spondylosis. Additionally we desired to use a CME normal reference range (NRR) to compare and contrast movement patterns identified from 3 specific structural pathologic conditions: intervertebral disc, facet joint, and nerve root compression. METHODS: Computer-aided CME was used before and after intervention, in a cohort study design, to record lumbar range of movement along with pain, disability, and health self-report questionnaires in 17 participants who received image-guided facet, epidural, and/or rhizotomy intervention...

BACKGROUND: Low-value care, defined as care with a lack of benefit, can lead to higher health care costs, inconvenience to patients and, in some cases, harm to patients. The objectives of this study are to conduct exploratory analyses to understand how frequently selected low-value tests are ordered, to assess the degree of variation in ordering that exists across regions and practices, and to identify services that may warrant further investigation and targeted interventions. METHODS: We conducted a population-based retrospective cohort study using administrative health care databases from Ontario to identify rates of use of the following low-value services between fiscal years 2008/09 and 2012/13: computed tomography (CT) or magnetic resonance imaging (MRI) after a diagnosis of low back pain, Papanicolaou testing in women less than 21 years of age or older than 69 years of age and repeated dual-energy X-ray absorptiometry (DEXA) scanning within 2 years of an index scan...

A 64-year-old man was admitted with sudden back and chest pain. He had undergone aortic valve replacement 5 years earlier. Enhanced computed tomography showed acute type A non-communicating aortic dissection. He was initially treated with supportive medical therapy. Since he was restless, he was placed on a respirator. He went into sudden shock 6 h after onset. Percutaneous cardiopulmonary support was administered, and coronary arteriography showed progression of the dissection to the left main trunk. Percutaneous coronary intervention was performed...

Choosing Wisely was launched by the American Board of Internal Medicine in April 2012 as a patient- and clinician-targeted campaign to reduce potentially unnecessary "low-value" medical services. The campaign's impact on low- and high-value care beyond its first year is unknown; furthermore, it is unknown whether some patients such as members of consumer-directed health plans and people residing in different US regions have responded more than others. To evaluate the impact of Choosing Wisely, we used commercial insurance claims to track changes in the use of low-value imaging (x-ray, computed tomography, and magnetic resonance imaging) for back pain before and after the campaign began, a period running from 2010 to 2014...

Osteoid osteomas of the spine are benign bone tumors typically presenting with progressive pain without neurological deficit. This report presents a case of an osteoid osteoma in the lumbar spine associated with radicular pain. The patient, a young male athlete, presented with severe chronic nightly left low back pain radiated to the ipsilateral lower extremity who failed to respond to physical therapy and analgesic medications. Initial radiologic examination was reported as normal, but closer inspection of the T1- and T2-weighted magnetic resonance image as well as technetium-99m total body bone scan and a computed tomography scan revealed a bony lesion in the left transverse process of the L4 vertebra consistent with the diagnosis of osteoid osteoma...

BACKGROUND: Up to 15% of all spontaneous subarachnoid hemorrhages (SAH) have a non-aneurysmal SAH (NASAH). The evaluation of SAH patients with negative digital subtraction angiography (DSA) is sometimes a diagnostic challenge. Our goal in this study was to reassess the yield of standard MR-imaging of the complete spinal axis to rule out spinal bleeding sources in patients with NASAH. METHODS: We retrospectively analyzed the spinal MRI findings in 190 patients with spontaneous NASAH, containing perimesencephalic (PM) and non-perimesencephalic (NPM) SAH, diagnosed by computer tomography (CT) and/or lumbar puncture (LP), and negative 2nd DSA...
