Evaluation of vertebral bone mineral density in scoliosis by using quantitative computed tomography.

PURPOSE: Scoliosis is described as a lateral curvature of the spine. We aimed to evaluate bone mineral density (BMD) in patients with scoliosis by using quantitative computed tomography (QCT) and compare the BMD of idiopathic and congenital scoliosis patients. MATERIAL AND METHODS: Forty-three patients aged 1 to 40 years with idiopathic, congenital, or neuromuscular scoliosis and 41 matched controls of the same sex and approximate age were included in the study. Measurements of BMD were performed by QCT analysis for each vertebral body from T12 to L5, and mean BMD was calculated for each case. RESULTS: Twenty-two of the patients with scoliosis were idiopathic, 15 were congenital, four were neuromuscular, and two were neurofibromatosis. The mean BMD values of patients with scoliosis were significantly lower compared with the control group (106.8 ± 33.4 mg/cm3 vs. 124.9 ± 29.1 mg/cm3, p = 0.009). No significant difference in BMD values was found between idiopathic and congenital scoliosis patients (p > 0.05). CONCLUSIONS: This study illustrated that the vertebral body BMD values of the patients with scoliosis were significantly lower than those seen in the control group.

Vertebral body bone mineral density in patients with lumbar spondylolysis: a quantitative CT study.

PURPOSE: Spondylolysis is known to be a part of a disease process, which describes a defect in the pars interarticularis of vertebra. We aimed to use quantitative computed tomography (QCT) to measure vertebral body bone mineral density (BMD) in patients with lumbar spondylolysis and compare it with readings in controls. METHODS: Forty symptomatic patients with lumbar spondylolysis aged 18-52 years and 40 matched controls of same sex and approximate age (±2 years) were included in the study. Measurements of BMD were performed by QCT analysis for each vertebral body from T12 to L5 and mean BMD was calculated for each case. RESULTS: Of 40 patients, 22 (55%) demonstrated L5 spondylolysis, 14 (35%) L4 spondylolysis, three (7.5%) L3 spondylolysis, and one (2.5%) L2 spondylolysis. Spondylolisthesis was found in 29 patients (73%). Patients with spondylolisthesis were significantly older than patients without spondylolisthesis (42±6.9 vs. 37.2±5.4, P = 0.024). Mean BMD value of the patient group was significantly lower than that of the controls (105±24 mg/cm³ vs. 118.7±25.6 mg/cm³, P = 0.015). Subgroup analysis of 19 patients and 19 controls under the age of 40 revealed that the mean BMD value of the patients was significantly lower than that of the controls in the younger age group as well (108.7±23.5 mg/cm³ vs. 130±25.8 mg/cm³, P = 0.009). CONCLUSION: This study demonstrated that patients with spondylolysis had significantly lower mean vertebral body BMD compared with controls.

Evaluation and comparison of radiologic-pathologic findings in invasive cribriform carcinoma of the breast.

BACKGROUND/AIM: This study aimed to report invasive cribriform carcinoma (ICC) with radiological and histopathologic correlations. MATERIALS AND METHODS: Seventy patients with ICC were classified into two groups; pure ICC patients and patients with >50% cribriform carcinoma component were included in group 1, while patients with <50% cribriform carcinoma component were included in group 2. All patients were reviewed according to American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS) lexicon of mammography (MG), ultrasonography (US), and magnetic resonance imaging (MRI). One-way analysis of variance tests and t-tests were used for analysis. P < 0.05 was accepted as statistically significant. RESULTS: Eighteen patients were in group 1 and 52 were in group 2. All patients had MG and US, while 24 patients needed MRI. According to MG ACR BI-RADS lexicon evaluation, irregular shape, spiculated margin and indistinct margin, and high density were statistically significantly higher in group 2 than the other group (respectively P = 0.001, P = 0.001, and P= 0.04). Equal density was statistically significantly higher in group 1 than the other group (P = 0.008). According to US ACR BI-RADS lexicon evaluation, irregular shape, spiculated margins, angular margins, microlobulated margins, and nonparallel orientation were more common US findings in group 2 than the other group (respectively P = 0.001, P = 0.001, P = 0.003, P = 0.04, and P = 0.04). The rate of parallel orientation was higher in group 1 than the other group (P = 0.02). CONCLUSION: Few cases showed benign characteristics and most ICCs appear with typical features of malignancy. Radiologic features of ICC could be better understood and would be helpful for radiologists in diagnosing this rare type of malignancy.

How Turkish radiology residents access information related to their profession in this social media and smartphone era.

PURPOSE: To evaluate the frequency of mobile technology and social media usage among radiology residents and their access to professional information. MATERIALS AND METHODS: A questionnaire consisting of 24 questions prepared using Google Drive was sent via e-mail to 550 radiology residents throughout the country. Of the 176 participating residents, 74 completed the survey via the internet, and 102 completed it at three different national radiology meetings. Response rates and its relationship with responses given to different questions were assessed. RESULTS: Hundred two male and 74 female residents participated in the survey. 141 (81.3%) residents thought that they had appropriate internet access in their department. The number of residents using a smartphone was 153 (86.9%). The android operating system (70, 45.8%) was the preferred operating system of respondants. Only 24 (15.7%) of the smartphone users thought that there were enough radiology related applications. "Radiology assistant" (18.9%), "Radiopedia" (7.8%) and "Radiographics" (7.8%) were the most utilized applications. Of the smartphone users, 87(56.9%) stated that they used cell phones in order to find radiological information, and the most used web pages were Google (165, 93.8%), Radiopaedia.org (129, 73.3%), Radiologyassistant.nl (135, 76.7%), and Pubmed (114, 64.8%). Social media usages were as follows: None (10, 5.7%), Facebook (139, 79%), Twitter (55, 31.3%), Google + (51, 29%) and YouTube (44, 25%). CONCLUSION: While smartphone usage rates among the residents were high, the use of radiology specific applications was not common. Social media usage was very common among residents.
