conclusions in view of the limitations of the above-mentioned modalities, liver biopsy remains the gold standard method for documentation of diagnosis and estimation of disease severity in nafld. context considering the increasing prevalence of obesity and insulin resistance syndrome worldwide, non-alcoholic fatty liver disease (nafld) has become a major health concern. early diagnosis and prop...

PURPOSE This review aims to discuss the methodological aspects of dedicated molecular breast imaging (MBI) using 99mTc-sestamibi as radiotracer to guide biopsy of occult or unclear breast lesions on mammography (MG) and ultrasound (US) that are suspicious on MBI (BI-RADS criteria 4 and 5), including its advantages, limitations and future clinical applications. METHODS Literature search was pe...

OBJECTIVE The increasing importance of breast MRI in the diagnostic processes concerning breast cancer yield often lesions that are visible on MRI only. To assess the nature of these lesions, pathologic analysis is necessary. Therefore, MR-guided biopsy should be available. Breast MRI at 3T has shown advantage over 1.5T. Unfortunately, current equipment for MR-guided biopsy is better suited for...

BACKGROUND Although endobronchial ultrasound (EBUS)-guided transbronchial biopsy (TBB) has been shown to increase the diagnostic yield over conventional bronchoscopic techniques, an important issue regarding the optimal number of biopsy specimens required has not been thoroughly investigated. OBJECTIVES We sought to examine whether the number of biopsy specimens taken was associated with the ...

PURPOSE The purpose of this study was the clinical evaluation of ultrasound-guided biopsy in comparison with ultrasound-guided fine-needle aspiration biopsy of identical, non-palpable breast lesions. MATERIALS AND METHODS From August 1997 until July 1998, 73 ultrasound-guided biopsies were performed in 66 patients with non-palpable lesions of the breast. In 18 patients (age 33-77 years) with ...

background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...

CONTEXT Lymphoepithelial cysts are rare benign lesions of the pancreas. Endoscopic ultrasound guided fine needle aspiration (FNA) has reportedly been helpful in reaching a diagnosis of lymphoepithelial cyst. In cases where it may be difficult to obtain a diagnosis using FNA a histological sample may be obtained using EUS guided Trucut biopsy. CASE REPORTS We describe two cases of lymphoepithe...

Background: An alveolar adenoma is a benign lung lesion that presents as solitary pulmonary nodule. Only few reports have been published on this disease, which typically diagnosed by wedge resection. Case presentation: We present 39 year old woman with multiple co-morbidities an incidental was utilizing CT-guided biopsy, she then suffered rare complication necessitating ICU admission. Conclusio...

PURPOSE We aimed to investigate prostate cancer detection rate of magnetic resonance imaging (MRI)-guided biopsy and to elucidate possible relations to the number of prior negative transrectal ultrasonography (TRUS)-guided biopsies. MATERIALS AND METHODS Eighty-seven consecutive patients (mean age, 65.0 years; mean prostate-specific antigen, 13.3 ng/mL) with at least one prior negative TRUS-g...

The aim of this study was to compare accuracy of an image guided percutaneous core needle biopsy (PCNB), using ultrasound or computed tomography, to PCNB without image guidance in the diagnosis of palpable soft tissue tumours. One hundred forty patients with a suspected soft tissue sarcoma underwent a percutaneous core needle biopsy with or without image guidance. One hundred eleven patients ha...
