BACKGROUND AND OBJECTIVE Nicotine reportedly is a risk factor for periodontitis, but accurate data regarding nicotine-induced alveolar bone loss is lacking. The aim of this study was to quantitatively assess alveolar bone loss in ligature- and nicotine-induced periodontitis in rats using micro-computerized tomography (micro-CT).

AIM To determine the specific imaging criteria on contrast-enhanced multidetector computed tomography (MDCT) for differentiating between tuberculosis and lymphoma in mediastinal lymph nodes. MATERIALS AND METHODS The anatomical distribution and enhancement patterns of mediastinal lymph nodes on contrast-enhanced MDCT were reviewed in 37 patients with(More)
BACKGROUND Tuberculosis (TB) of the cervical lymph nodes may mimic lymphoma. OBJECTIVE To evaluate multidetector-row computed tomographic (MDCT) imaging criteria for differentiating between the two diseases. MATERIALS AND METHODS We retrospectively reviewed the anatomical distribution and CT enhancement patterns of the nodes in 81 patients, 27 (33%)(More)
OBJECTIVE To determine magnetic resonance imaging (MRI) characteristics of abdominal tuberculous lymphadenopathy. DESIGN Twenty-six consecutive patients (20 men, 6 women; mean age 38 ± 14 years) with documented tuberculosis (TB) in the abdominal lymph nodes were recruited and retrospectively analysed for contour, size, enhancement patterns, signal(More)
BACKGROUND The enlarged mediastinal lymph nodes caused by tuberculosis (TB) and chronic lymphocytic leukaemia (CLL) are similar, sometimes resulting in misdiagnosis of the two diseases. OBJECTIVE To determine the differential characteristics of enlarged mediastinal lymph nodes caused by TB and CLL using multidetector-row computed tomography (MDCT). (More)
