PURPOSE To evaluate any association between tumor apparent diffusion coefficient (ADC) values and axillary lymph node metastasis (ALNM) in early-stage invasive ductal carcinoma. MATERIALS AND METHODS Records of 270 invasive ductal carcinoma patients with stages T1 and T2 disease who underwent breast magnetic resonance imaging, including diffusion-weighted(More)
Isolated left ventricular (LV) apical hypoplasia is a rare congenital cardiac anomaly which is not accompanied by other cardiac abnormalities, with the exception of two cases. We report a case of a 33-year-old male patient with isolated LV apical hypoplasia combined with infundibular pulmonary stenosis and aortic stenosis. We review a literature focusing on(More)
OBJECTIVE The aim of the study was to assess the effectiveness of the adaptive statistical iterative reconstruction (ASIR) for dual-energy computed tomography pulmonary angiography (DE-CTPA) with a reduced iodine load. MATERIALS AND METHODS One hundred forty patients referred for chest CT were randomly divided into a DE-CTPA group with a reduced iodine(More)
Arachnoid cysts (AC) are cerebrospinal fluid collections surrounded by an arachnoid membrane. They are mostly of developmental anomalies and represent 1% of all intracranial space-occupying lesions (1). Although ACs are usually asymptomatic, they may present clinical symptoms by complications such as rupture with subdural hematoma, intracystic hemorrhage,(More)
OBJECTIVE The purpose of this study was to evaluate the correlation between the dilatation of the spinal epidural venous plexus (SEVP) and the amount of epidural fat (EF). METHODS Between January 2007 and January 2012, 116 patients with prominent EF and 116 control subjects without prominent EF were included in this study. On the lumbar MR images, we(More)
PURPOSE The purpose of this study was to investigate the clinical feasibility of spectral analyses using dual-layer detector spectral computed tomography (CT) in acute intracerebral haemorrhage (ICH). MATERIAL AND METHODS We retrospectively reviewed patients with acute ICH who underwent CT angiography on a dual-layer detector spectral CT scanner. A(More)
The aim of this study was to determine the relationship between lobar severity of emphysema and lung cancer using automated lobe segmentation and emphysema quantification methods.This study included 78 patients (74 males and 4 females; mean age of 72 years) with the following conditions: pathologically proven lung cancer, available chest computed(More)
RATIONALE Detection of skull metastases is as important as detection of brain metastases because early diagnosis of skull metastases is a crucial determinant of treatment. However, the skull can be a blind spot for assessing metastases on routine brain magnetic resonance imaging (MRI). To the best of our knowledge, the finding of skull metastases on(More)
RATIONALE Brain arteriovenous malformations (AVMs) are congenital vascular abnormalities involving abnormal connections between arteries and veins. In clinical practice, imaging studies help evaluate feeding arteries, niduses, draining venous systems, and coexisting complications in patients with brain AVM. They also have an impact on decision-making(More)
OBJECTIVE To evaluate the computed tomography (CT) findings and clinical characteristics of pulmonary tuberculosis (TB) in patients with emphysema, compared with those without emphysema. MATERIALS AND METHODS Thirty-nine patients (M:F = 36:3; mean age, 64.8 years) who were diagnosed with chronic obstructive pulmonary disease and had emphysema in(More)
