“…In 25% of patients there was no specific pulmonary disease. These results were in conformity with previous reports depicting that in patients who were exposed to long-term smoke of organic fuels could develop a wide range of pulmonary problems such as constrictive disease, interstitial lung disease, cancer, asthma and recurrent infections of the lower respiratory tract [10][11][12][13][14]. In a meta-analysis by Hu et al it has been also shown that long-term exposure to the smoke of organic materials may increase the risk of constrictive-obstructive disease significantly [15].…”

Still in many places all over the world including East Azerbaijan Province and particularly in rural areas, women use traditional methods such as using oven and organic fuels (wood, turd) to bake bread. It has been shown that the smoke organic fuels in places with inadequate ventilation for a long term may cause a range of problems in the respiratory system. CT angiography is a good and less invasive method in evaluating pulmonary vascular system. This study tried to compare CT angiography findings in the lungs of bread-cooking women with respiratory complaints and females with COPD and no history of bread cooking. In this casecontrol setting, 36 patients in the bread-cooking group (case) and 36 patients with COPD in the control group underwent lung CT angiography. Pathologic findings including dilation of the bronchial arteries, hyper vascularization of the bronchial arteries, changes in pulmonary trunk diameter, silent embolism and any other abnormal changes were documented and compared between the two groups. The mean duration of bread-cooking was 4.78±3.17 years (2-12). Abnormal vascular findings in lung CT angiographies of the bread-cooking women with respiratory complaints were dilation of the bronchial arteries (22.2%), hyper vascularization of the bronchial arteries (8.3%), silent embolism (11.1%) and parenchymal emphysematous changes (13.9%). They were documented in the COPD group in 36.1%, 27.8%, 27.8% and 3.33% of the patients, respectively. Accordingly, the frequency of hyper vascularization of the bronchial arteries and parenchymal emphysematous changes was significantly higher in the COPD group than in the bread-cooking women. In contrast, the mean diameter of the pulmonary trunk was significantly higher in the bread-cooking group (3.32 vs. 3.17 cm). Abnormal findings in lung CT angiography of bread-cooking women with respiratory symptoms are frequent and in some cases, they are different from findings in the lungs of women with COPD and no previous history of breadcooking.

“…10,36 Ultrasonography is also inaccurate in delineating fractures and differentiating soft tissues of the contents of a traumatized globe; it is operator dependent and contraindicated when a ruptured globe is suspected. 15,26,[37][38][39] Another rather novel imaging modality that has been suggested in cases with orbital fractures is CBCT. The major advantage of this modality over conventional CT is the reduced X-ray exposure to the eyes.…”

Objectives: To compare the diagnostic performance of ultrasonography and CBCT against CT in detecting orbital floor fractures. Methods: A total of 120 orbits with clinical suspicion of isolated orbital floor fractures underwent multislice CT scanning with coronal reconstruction; orbital ultrasonography using a standard machine equipped with a 7-to 10-MHz linear transducer; and CBCT. Patients with severe head and face injuries were not included. The diagnostic performance of ultrasonography and CBCT was reported assuming conventional CT as the imaging method of choice. Results: According to CT findings, fractures of the floor were present in 39 orbits. The sensitivity, specificity, positive-predictive value and negative-predictive value of ultrasonography in detecting orbital floor fractures were 87.2%, 100%, 100% and 94.2%, respectively. The corresponding values for CBCT were 97.4%, 97.5%, 95.0%, and 98.8%, respectively. Areas under the receiver operator characteristics curves of orbital floor fracture detection were 0.94 for ultrasonography and 0.98 for CBCT. Conclusions: When conventional CT cannot be performed in patients with clinically suspected orbital floor fracture and no severe or complex head and face injuries, CBCT could be used in detecting fractures as a reliable surrogate. Because of a lower sensitivity of ultrasonography, however, its use is limited in this regard.

“…Javadrashid et al [11] compared the usefulness of 4 imaging modalities in visualizing various foreign bodies of different sizes. In this study, all foreign bodies except wood were visualized best using CT. Wood could only be detected using US, and, then, only when fragments were greater than 0.5 mm in size.…”

Visibility of different foreign bodies in the maxillofacial region using plain radiography, CT, MRI and ultrasonography: anin vitrostudy

Abstract: In cases with suspected foreign bodies in the maxillofacial region, CT seems to be the optimal initial imaging study. Wood, however, could only be detected using ultrasonography.
