Detecting bone lesions in X-ray under diverse acquisition conditions.

Purpose: The diagnosis of primary bone tumors is challenging as the initial complaints are often non-specific. The early detection of bone cancer is crucial for a favorable prognosis. Incidentally, lesions may be found on radiographs obtained for other reasons.

Osteophytes' position in subjects with DISH and right-sided aorta: verification of the 'aortic pulsation protective effect' theory.

Objectives: To validate in a large cohort with right-sided aorta the theory that thoracic right-sided flowing osteophytes in DISH results from a 'protective' effect of the pulsating descending left-sided thoracic aorta.

Methods: Chest CTs of patients with DISH and right-sided aorta and controls with DISH and left-sided aorta were evaluated and compared on each intervertebral space (IS) for the location of the aorta (right, left, centre) and the location of the osteophyte relative to the aorta (contralateral, ipsilateral, bilateral).

Results: The study and control cohorts included 31 and 35 subjects, respectively (male 22/9 and female 27/8; median age 64.

Reduction of the Vertebral Bone Mineral Density in Patients with Hodgkin Lymphoma Correlates with Their Age and the Treatment Regimen They Received.

Nowadays, Hodgkin lymphoma (HL) has become highly curable. The young age at diagnosis and long life expectancy emphasize the importance of preventing long-term treatment side effects, including bone mineral density (BMD) loss, in these patients. We aimed to evaluate the effects of first-line therapeutic modalities on BMD dynamics in HL patients, intending to identify individuals at risk for osteopenia.

CT-Ultrasound Fusion for Abdominal Aortic Aneurysm Measurement.

To evaluate the potential for surveillance of abdominal aortic aneurysms without ionizing radiation exposure and without the risks of iodinated contrast administration, the accuracy of fusion of CT angiography (CTA) with ultrasound (US) was compared with conventional US in 14 patients. The mean measurement difference between conventional US and CTA was 0.50 cm, compared with 0.
