Early stage cervical cancer: role of magnetic resonance imaging after conization in determining residual tumor.
Abstract BACKGROUND: Although magnetic resonance imaging (MRI) is currently indispensable in the management of cervical cancer, its role in determining residual tumor in patients with cervical cancer after conization is not well known. PURPOSE: To evaluate the value of MRI after conization in determining residual tumor in patients with FIGO stage IA-IB1 cervical cancer. MATERIAL AND METHODS: In this retrospective study, 55 patients underwent conization followed by preoperative MRI and definitive surgery. Two radiologists evaluated the presence of residual tumor on MRI. MRI and preoperative clinical varia...

Angiomyolipoma with minimal fat: differentiation of morphological and enhancement features from renal cell carcinoma at CT imaging.
Abstract BACKGROUND: Angiomyolipoma (AML) with minimal fat may mimic renal cell carcinoma (RCC) and is difficult to distinguish from RCC with imaging studies alone. Precise diagnostic strategies have been explored to discern AML with minimal fat from RCC. PURPOSE: To compare the morphological and enhancement features of AML with minimal fat with those of size-matched RCC on computed tomography (CT). MATERIAL AND METHODS: Our study included 143 pathologically proved renal tumors (29 AML with minimal fat: mean diameter, 2.5 cm; range, 1.2-4 cm; 114 RCC: mean diameter, 2.8 cm; range, 1....

Revival of monophasic contrast injection protocols: superiority of a monophasic injection protocol compared to a biphasic injection protocol in high-pitch CT angiography.
Abstract BACKGROUND: Biphasic injection protocols are frequently used because they yield homogenous contrast enhancement. We hypothesize that with faster scanners and shorter scan times, biphasic injection protocols are no longer necessary. PURPOSE: To evaluate whether a monophasic injection protocol is equivalent to a biphasic protocol in terms of contrast enhancement and homogeneity. MATERIAL AND METHODS: Repeated high-pitch CTA (pitch 3) and conventional standard-pitch computed tomography angiography (CTA) (pitch 1.2) from the cervical region to the symphysis was performed in seven beagles (11.2&thins...

Prediction of anatomical lung volume using planimetric measurements on chest radiographs.
Abstract BACKGROUND: The anatomical lung volume is conventionally measured by computed tomography (CT). However, chest radiographs could be considered as an alternative method with low cost and low radiation. PURPOSE: To predict the anatomical lung volume using planimetric measurements of chest radiographs. MATERIAL AND METHODS: In total, 119 participants (M:F ratio = 66:53; age, 53.7 ± 9.6 years) who underwent chest CT for lung cancer screening were enrolled. The lung volume on CT was measured as a reference for the anatomical lung volume. To eliminate the bias from th...

Diffusion-weighted magnetic resonance imaging in the differentiation of endometriomas from hemorrhagic cysts in the ovary.
Abstract BACKGROUND: The classic magnetic resonance imaging (MRI) feature of endometriomas is the shading sign, which is characterized by T2-shortening in ovarian cystic lesions that are hyperintense on T1-weighted images. The shading sign is infrequently observed in hemorrhagic ovarian cysts.
