    False Positive Computed Tomography Imaging for Coronavirus-2019
    (2021) Akkucuk, Mehmet Husamettin; Karadas, Mehmet Akif; Seviner, Meltem; Demir, Tayfun Anil; Doganay, Elif Kilicli; 0000-0003-4569-1143; 0000-0002-4719-2535; AAJ-2828-2021; AAJ-1600-2021
    A 79-year-old female patient presented to the emergency unit with cough and severe shortness of breath. Due to a bilateral multilobular ground glass density result from thoracic tomography, the patient was admitted to intensive care with the preliminary diagnosis of corona virus-2019 (COVID-19), and a continuous positive airway pressure was applied. A polymerase chain reaction (PCR) test was performed, and treatment with hydroxychloroquine and azithromycin was initiated. At the same time, the patient with an arterial blood pressure of 190/100 mm/hg was administered with diuretic treatment to reduce lung congestion. The follow-up computed tomography of the patient showed rapid recovery, and ground glass appearances had completely resolved. The PCR was negative and the patient was diagnosed with acute lung edema. The treatment was prescribed, and the patient was discharged from the hospital. Thoracic tomography findings are useful in early period for COVID-19 diagnosis; however, it may show similar results as other diseases that cause respiratory failure and lead to misleading interpretations.

    Diagnostic importance of maximum intensity projection technique in the identification of small pulmonary nodules with computed tomography
    (2020) Guleryuz Kizil, Pinar; Hekimoglu, Koray; Coskun, Mehmet; Akcay, Sule; 0000-0001-5630-022X; 0000-0002-0805-0841; 0000-0002-8360-6459; 32718138; AAM-4120-2021; AAD-9097-2021; AAB-5175-2021
    Introduction: In this retrospective study, the aim is to determine the sensitivity of maximum intensity projection (MIP) technique to 3 mm-thick axial sections in patients with small pulmonary nodules identified via examination using computed tomography (CT), and to identify whether this technique provides significant reduction in duration of nodule evaluation. Materials and Methods: A total of 69 patients (339 nodules) who underwent thoracic tomography due to various complaints and in whom pulmonary nodules were identified as a result of the examination were included in the study. Their axial sections that are 3 mm-thick and MIP sections obtained in the axial plane were evaluated by two different radiologists at different times by keeping time. the dimensions and evaluation times of the nodules were recorded separately for each method. Results: Evaluation compatibility between the radiologists was found to be 86.8% and it was considered to be perfectly compatible. Sensitivity of the 1st radiologist in the detection of nodules with MIP was 81.4%, whereas the sensitivity of the 2nd radiologist was 83.4%. In the evaluation for the reporting periods, when the duration of evaluation of MIP images were compared with the gold standard, a statistically significant reduction was found in the reporting times of both radiologists (p< 0.01). Conclusion: It was found that utilization of MIP images as an alternative method to detect pulmonary modules reduces the duration of evaluation significantly and provides the ability to detect nodules with high sensitivity. According to these data, MIP imaging may be preferred as an adjunct method in the evaluation of lung nodules as it provides fast and reliable information besides classical axial sections.
