Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent cancers.The Task Force Committee of the Korean Society Thyroid Radiology (KSThR) developed recommendations for optimal use tumors 2012.As new meaningful evidences have accumulated, KSThR decided revise guidelines.The revised guideline based on comprehensive analysis current literature expert consensus.
Background The diagnostic abilities of multimodal large language models (LLMs) using direct image inputs and the impact temperature parameter LLMs remain unexplored. Purpose To investigate ability GPT-4V Gemini Pro Vision in generating differential diagnoses at different temperatures compared with radiologists
Aggregate published data on the imaging of pulsatile tinnitus as a step toward building framework for an evidence-based approach to diagnostic this symptom. A systematic review was performed. PUBMED and EMBASE were searched December 1, 2021 English-language articles tinnitus. Articles that involved non-standard techniques those focused management excluded. Extracted included: number males females; signs, symptoms, physical examination findings with associated patient counts; findings; count...
<h3>BACKGROUND AND PURPOSE:</h3> Dynamic contrast-enhanced T1-weighted perfusion MR imaging is much less susceptible to artifacts, and its high spatial resolution allows accurate characterization of the vascular microenvironment lesion. The purpose this study was test predictive value initial final area under time signal-intensity curves ratio derived from dynamic differentiate pseudoprogression early tumor progression in patients with glioblastomas. <h3>MATERIALS METHODS:</h3> Seventy-nine...
To determine normal reference values of liver elasticity and measurement reliability by using real-time shear-wave elastography (SWE) in patients with a range ages body mass index (BMI) measurements, presence or absence hepatic steatosis.The institutional review board approved this study, informed consent was waived because the retrospective nature study. Two hundred thirty-eight who underwent SWE ultrasonography-guided biopsies on same day were identified retrospectively. The median...
<h3>BACKGROUND AND PURPOSE:</h3> Intravoxel incoherent motion can simultaneously measure diffusion and perfusion characteristics. Our aim was to determine whether the parameters derived from intravoxel could act as imaging biomarkers for distinguishing recurrent tumor treatment effect in patients with glioblastoma. <h3>MATERIALS METHODS:</h3> Fifty-one pathologically confirmed (<i>n</i> = 31) or 20) were assessed by means of MR imaging. The histogram cutoffs 90th percentiles normalized CBV...
Background The diagnostic performance and unnecessary biopsy rates for evaluation of thyroid nodules varies among the current society guidelines. We hypothesized that different guidelines are largely determined by size thresholds used as cutoff values determine when to a nodule. Purpose To compare malignancy risk, performance, three evaluate changes according nodule biopsy. Materials Methods This retrospective study included 3323 consecutive from 3190 patients between January 2013 December...
To determine the utility of intravoxel incoherent motion (IVIM)-derived perfusion and diffusion parameters for differentiation atypical primary central nervous system lymphoma (PCNSL) from glioblastoma in patients who do not have acquired immunodeficiency syndrome.The institutional review board approved this retrospective study waived informed consent requirement. Sixty with either pathologic analysis-confirmed PCNSLs (n = 19) or glioblastomas 41) were assessed by using maximum IVIM-derived...
