Introdution: Seizure is the most common neurologic symptom of neonatal period and brain CT scan can be helpful in finding of its etiology. The purpose of present study was to evaluate brain CT scan findings of admitted neonates with clinical seizure and its correlation with clinical findings. Methods: In a retrospective descriptive study, medical records and brain CT scan findings of neonates ...
Background and Aim: In recent years, CT scan has become available as an alternative to conventional radiography. To date, the utility of Waters view in detecting midface fractures has been rarely evaluated. The aim of this study was to compare the diagnostic accuracy and reliability of Waters radiography with CT scan in detecting midface fractures. Materials and Methods: In this tests evaluatio...
Aims and objectives: Vocal cord palsy (VCP) can be definitely depicted on computed tomograpy (CT) scan by identifying key points at the level of true vocal cords and aryepiglottic folds. There are various VCP mimics and imaging shortcomings, and these can usually be circumvented by thoughtfully assessing the scan plan and level, and a diligent search for additional characteristics. Materials an...
PURPOSE This study aimed to investigate the deviation of landmarks from horizontal or midsagittal reference planes according to the methods of establishing reference planes. MATERIALS AND METHODS Computed tomography (CT) scans of 18 patients who received orthodontic and orthognathic surgical treatment were reviewed. Each CT scan was reconstructed by three methods for establishing three orthog...
A 1-year-old boy had ophthalmologic findings of a retinoblastoma in the right eye. Noncontrast and contrast computed tomography (CT) demonstrated a characteristic calcified lesion of retinoblastoma in the right globe and a nonenhancing, well circumscribed, extraconal mass in the superolateral aspect of the left orbit (fig. 1 A). This mass, measuring 18 H, displaced the optic nerve medially. An ...
A 73-year-old man with history of prostatic adenocarcinoma radical prostatectomy underwent 99mTc-MDP whole-body bone scan and subsequent 68Ga-labeled prostate-specific membrane antigen (PSMA) ligand PET/CT for restaging due to a gradual rise of prostate-specific antigen levels. Whole-body bone scan showed two focal zones of slightly increased uptake in the right fronto-par...
Introduction: Today, several methods are used for detecting COVID-19 such as disease-related clinical symptoms, and more accurate diagnostic methods like lung CT-scan imaging. This study aimed to achieve an accurate diagnostic method for intelligent and automatic diagnosis of COVID-19 using lung CT-scan image processing techniques and utilize the results of this method as an accurate diagnostic...

Figure 1. The initial staging FDG PET/CT images (Figure 1A [Maximum intensity projection (MIP) image]), showed intense hypermetabolic retroperitoneal lymph nodes (SUVmax:8,4) (arrow heads in Figure 1B [coronal PET, CT and fusion PET/CT images] and C [axial PET, CT and fusion PET/CT images]) and segmental FDG uptake in the inferior vena cava below renal veins suggestive for tumor thrombus (SUVma...
High-resolution axial and coronal computed tomographic (CT) scans were compared with coronal and sagittal complex motion tomograms in patients with suspected middle ear cholesteatomas. Information on CT scans equaled or exceeded that on conventional complex motion tomograms in 16 of 17 patients, and in 11 it provided additional information. Soft-tissue resolution was superior with CT. In 14 pat...
