We report a rare case of left internal mammary artery (LIMA) originating from the thyrocervical trunk (TCT), which arose directly aortic arch. A patient in their 70s presented with bilateral distal carotid aneurysms, diagnosed through computed tomography angiography performed for headache evaluation. Transfemoral cerebral confirmed aneurysms and incidentally revealed anomalous origins TCT LIMA, as well vertebral arising This emphasizes importance recognizing such anatomical variations prior...
This study aimed to assess the diagnostic efficacy of Korean Thyroid Imaging Reporting and Data System (K-TIRADS) features for distinguishing follicular thyroid adenoma (FTA) from carcinoma (FTC).From January 2013 July 2016, 46 neoplasms in 45 patients who underwent preoperative ultrasonography (US) surgery were included. The US each nodule retrospectively evaluated by a single radiologist using picture archiving communication system. indices K-TIRADS calculated according whether category 4...
Mycosis fungoides is the most common type of cutaneous T-cell lymphoma. There are a wide range treatments for early-stage and advanced-stage mycosis fungoides. Photodynamic therapy (PDT) has emerged as new treatment modality due to its safety efficacy. The aim this study was investigate efficacy PDT with methyl-aminolaevulinic acid (MAL) Ten patients were enrolled in study. A 16.8% MAL cream applied under occlusive dressing 3 h. lesion irradiated at 37.5 J/cm2 red light. underwent two...
Background: The objective of this study was to compare the postoperative neck pain and discomfort, swallowing difficulty, voice change after conventional open thyroidectomy (COT), endoscopic (ET), or robotic (RT) performed by a single surgeon. Methods: From January 2013 December 2017, 254 patients underwent COT, ET, RT surgeon completed symptom survey conducted in outpatient clinic three nurses. collected information on change. Results: Of patients, 169 32 53 RT. mean age groups 50.1, 44.5,...
Background Acute ischemic stroke (AIS) more frequently develops in patients with intracranial vertebral artery dissection (VAD) than extracranial VAD, and is associated possible poor clinical outcomes. The aim of this study to compare high-resolution magnetic resonance imaging (HR-MRI) findings features VAD without AIS. Methods Twenty-nine lesions from 27 (15 male 12 female patients; age range = 28-73 years) who underwent diffusion MRI 3T HR-MRI within seven days were included. We classified...
<h3>BACKGROUND AND PURPOSE:</h3> Time-of-flight MR angiography, though widely used after coil embolization, is associated with limitations owing to magnetic susceptibility and radiofrequency shielding following stent-assisted embolization. We evaluated the pointwise encoding time reduction radial acquisition (PETRA) sequence in subtraction-based MRA (qMRA) using an ultrashort TE relative TOF-MRA during follow-up of embolization for anterior circulation aneurysms. <h3>MATERIALS METHODS:</h3>...
Objective:The optimal threshold of the infusion volume cement has been a continuous subject in percutaneous vertebroplasty (PVP).This study verifies causal relationship between and clinical outcome, suggests parameters appropriate PVP.Methods: This is retrospective study.One hundred nine patients, who underwent PVP 2012 2015, were included study.Various factors such as patients' fracture levels, types, body volumes, rates, bone mineral densities, infused volumes analyzed.Cement ratios...
The ultrasonographic characteristics and difference for various subtypes of papillary thyroid carcinoma (PTC) are still unclear. aim this study was to compare the features PTC according its subtype in patients undergoing surgery.In total, 140 who underwent preoperative ultrasonography (US) surgery between January 2016 December were included. Korean Thyroid Imaging Reporting Data System (K-TIRADS) category each nodule retrospectively evaluated by a single radiologist, differences...
In ultrasound (US)-guided fine-needle aspiration (FNA) of solid thyroid nodules (STN) using liquid-based cytology (LBC), the most appropriate needle size for LBC remains unclear. This study compared cytological adequacy and complications associated with 23- 25-gauge needles in US-guided FNA STNs LBC. was performed consecutive patients by one radiologist to diagnose ≥ 5 mm largest diameter. The one-sampling technique through a single puncture multiple to-and-fro motions used each patient....
<h3>BACKGROUND AND PURPOSE:</h3> Contrast-enhanced T1-weighted sampling perfection with application-optimized contrasts by using different flip angle evolution (SPACE) the delay alternating nutation for tailored excitation (DANTE) pulse could suppress blood flow signal and provide a higher contrast-to-noise ratio of enhancing lesion-to-brain parenchyma than MPRAGE sequence. The purpose our study was to evaluate usefulness SPACE DANTE compared detecting brain metastases. <h3>MATERIALS...
Objective: To investigate the image quality, radiation dose, and intermodality agreement of cervical spine CT using spectral shaping at 140 kVp by a tin filter (Sn140-kVp) in comparison with those conventional 120 kVp.Materials Methods: Patients who had undergone Sn140-kVp (n = 58) 49) were included.Qualitative quality was analyzed 5-point Likert scale.Quantitative assessed measuring noise attenuation within central spinal canals C3/4, C6/7, C7/T1 levels.Radiation doses received patients...
This report presents a unique case of Caplan syndrome that mimicked accelerated progressive massive fibrosis. The patient, former coal miner, had been diagnosed with worker's pneumoconiosis 15 years prior and treated for rheumatoid arthritis over 20 years. Accelerated fibrosis the development multiple nodules cavitation in basal lungs were subsequently observed on serial CT scans. Here, manifestations are highlighted which
The purpose of this study is to compare the incidence possible complications cervical lateral screw fixation and achievements bicortical purchase using Roy-Camille, Magerl modified methods.Six fresh-frozen spine segments were harvested. Roy-Camille technique was applied C3 C4, C5, C6, C7 one side each cadaver. other nerve root injury, violation facet joint, vertebral artery bicortication examined at screwing level.No injury observed in any three methods. One segment method (8.3%), (5.6%),...
The etiologies of intracranial artery dissection are various, the exogenous as well inherited connective tissue disorders. We report on a patient who presented with diffuse subarachnoid hemorrhage had been suffered from essential thrombocythemia. He was diagnosed to multiple dissecting aneurysms left superior cerebellar artery, posterior inferior and right pericallosal treated endovascular coil embolization. Key Words: Aneurysm · Dissecting Essential thrombocythemia Subarachnoid hemorrhage.
Background Although time-of-flight magnetic resonance angiography (TOF-MRA) is widely used, it has limited usefulness for follow-up after stent-assisted coil embolization. Contrast-enhanced MRA (CE-MRA) and ultrashort echo time have been suggested as alternative methods visualization this procedure. Purpose To compare efficacy of pointwise encoding reduction with radial acquisition (PETRA) sequence in subtraction-based (qMRA), TOF-MRA, CE-MRA during the Neuroform Atlas embolization...
Objective . No previous studies regarding the appropriate timing of thyroid hormone discontinuation after hemithyroidectomy have been published. This study aimed to identify for levothyroxine among patients with papillary microcarcinoma (PTMC). Methods retrospectively evaluated 304 who underwent ≥1 attempt discontinue treating PTMC between January 2008 and December 2013. Fifty-three were excluded because preoperative hypothyroidism or hyperthyroidism, a history antithyroid therapy, no...
This study investigated the role of BRAF mutation analysis in thyroid fine-needle aspiration (FNA) samples compared to ultrasonographic and cytological diagnoses. A total 316 patients underwent ultrasonography (US)-guided FNA with BRAFV600E diagnose nodules. One hundred sixteen insufficient US images (n = 6), follow-up loss 43), or unknown final diagnosis 67) were excluded from study. Comparisons between diagnoses, performed. Of 200 nodules, there was 1 false negative 11 positive cases, 10 2...
Purpose: The Neuroform Atlas is a self-expandable and low-profiled stent that used for aneurysm neck scaffolding has been recently approved clinical practice in Korea.
