The cancer rate in our cohort of women who underwent MRI-guided breast biopsy was 29%. It varied according to the indication for the original MRI examination, but not according to the MRI features of the lesions.

MRI is an accurate method for predicting the extent of residual tumor after neoadjuvant chemotherapy; however, it may overestimate the residual disease, especially in cases showing a nest or rim tumor pattern and in those having combined lesions with ductal carcinoma in situ or multiple scattered nodules after neoadjuvant chemotherapy.

For lesions located in the surgical bed in patients after thyroidectomy, the distinction between recurrent thyroid cancer and nonrecurrent benign lesions cannot be made on the basis of the sonographic features. Fine-needle aspiration is helpful in determining the histologic nature of such lesions.

Epidemic adenoviral pneumonia may mimic bacterial pneumonia on radiographs. Findings that include bilateral and multifocal involvement on chest radiographs, normal or decreased WBC associated with lymphocytosis, and progression of illness despite extensive antibiotic therapy, help to differentiate epidemic adenoviral from bacterial pneumonia.

To evaluate the bone SPECT findings of vertebral hemangioma and their relationship to symptoms and MRI findings, the authors reviewed planar and SPECT bone scans and MR images of 15 vertebral hemangioma in 10 patients. All planar bone scan images demonstrated normal findings, except one, SPECT images demonstrated normal findings in 11 vertebral hemangioma less than 3 cm in diameter. Three of four vertebral hemangioma that were 3 cm or larger showed abnormally increased or decreased uptake on SPE

PURPOSE: To assess the value of repeat ultrasound-guided fine-needle aspiration (US-FNA) in nodules with benign cytological diagnosis. MATERIAL AND METHODS: One-hundred-and-eighty-seven patients undergoing repeat US-FNA were included after a benign cytological diagnosis had been made by the initial US-FNA. They were divided into a re-aspiration group, who underwent repeat US-FNA within 6 months for a discordant pathological and clinico-radiological result, and a follow-up aspiration group, who u

OBJECTIVE: The purpose of this study was to investigate the efficacy of ultrasonography in detecting an occult malignancy after surgery for breast cancer and to assess the imaging and clinical findings associated with a recurrence. METHODS: During a 4-year period, 3329 bilateral whole-breast ultrasonographic examinations were performed to detect occult malignancies clinically and mammographically in 1968 asymptomatic patients after breast cancer surgery. All questionable lesions were confirmed w

Asymptomatic subjects may have fat in RV on CT. However, these subjects show no RV dysfunction or significant ECG-abnormalities consistent with the diagnosis of arrhythmogenic RV dysplasia.

In this study group, most diagnosed cancers were in-situ lesions, and long-term follow-up showed that the sensitivity of SCNB was 82%. False-negative findings were frequent during the operators' learning period.

BACKGROUND: It remains uncertain whether MRI identification of additional foci of disease leads to improved outcome. We undertook a study to evaluate the influence of breast MRI on early and long-term outcome. METHODS: Among 1,271 patients undergone breast cancer surgery between January 2005 and December 2006, 785 patients were attempted for BCS. Operative approach and radiologic findings were compared according to MRI use. We reselected 615 patients with unilateral early-stage breast cancer tre
