BACKGROUND Ultrasound and CT-guided biopsy is a common procedure for histologic diagnosis of recurrence of head and neck squamous cell carcinoma. The present study describes a novel CT-guided endolaryngeal puncture site. METHODS AND RESULTS A 59-year-old man was treated for a T2N0M0 supraglottic laryngeal tumor by laser resection and bilateral lymph node dissection; exeresis was judged comple...

RATIONALE AND OBJECTIVES We aimed to evaluate whether implementation of a low-dose computed tomography (CT)-guided lung biopsy protocol, with the support of individual radiologists in the section, would lead to immediate and sustained decreases in radiation dose associated with CT-guided lung biopsies. MATERIALS AND METHODS A low-dose CT-guided lung biopsy protocol was developed with modifica...

OBJECTIVE To determine the re-biopsy rate, positive yield and safety profile of ultrasound guided fine needle aspiration cytology (FNAC) in cervical lymph nodes in terms of its complications and repeat procedures. STUDY DESIGN An analytical study. PLACE AND DURATION OF STUDY Department of Vascular and Interventional Radiology, Dow University Hospital, Dow University of Health Sciences, Kara...

We analyzed the improvement of prostate cancer detection rate (PCDR) in Chinese Han population and summarized the characteristics of prostate cancer (PCa) with the advancement of prostate biopsy technologies. From March 1999 to March 2015, 3762 patients underwent the systematic 6-, 8- or 13-core biopsy, guided by finger or transrectal ultrasound (TRUS) at our center. The PCDR under different PS...

OBJECTIVE To establish and verify the utility of plugging biopsy tracts, using a combination of Gelfoam slurry and torpedo in the prevention of post-biopsy bleeding in patients at high risk of post-procedure haemorrhage following ultrasound-guided percutaneous biopsy of solid organs. DESIGN Case series. SETTING Radiology Department of a regional hospital in Hong Kong. PATIENTS In our unit...

OBJECTIVE The purpose of this study was to evaluate the ability of sonography to depict and guide biopsies of mammographically suspicious microcalcifications and to reveal the mammographic features and histologic outcomes of lesions amenable to sonographically guided biopsy. SUBJECTS AND METHODS . Suspicious clusters of microcalcifications without other mammographic abnormalities were evaluat...

OBJECTIVE To evaluate the diagnostic outcomes of ultrasonography-guided core needle biopsy (US-CNB), US-guided vacuum-assisted biopsy (US-VAB), and stereotactic-guided vacuum-assisted biopsy (S-VAB) for diagnosing suspicious breast microcalcification. MATERIALS AND METHODS We retrospectively reviewed 336 cases of suspicious breast microcalcification in patients who subsequently underwent imag...

PURPOSE Although transrectal ultrasound-guided prostate biopsy is useful for diagnosing prostate cancer, it is a painful procedure. There are many methods for providing pain relief and for treating discomfort during the procedure, but occasionally these are reported to be of limited use. We aimed to evaluate the value and safety of midazolam-induced anesthetic transrectal ultrasound-guided pros...

Background Context. Computed tomography- (CT-) guided fine-needle aspiration biopsy of the vertebral body is an important tool in the diagnostic evaluation of vertebral osteomyelitis. The procedure is considered simple to perform and it is considered a safe procedure with few complications. Purpose. The purpose of this study was to describe an unusual complication due to a CT-guided fine-needle...
