RADIOLOGY. C-Arm Cone-Beam CT-guided Percutaneous Transthoracic Needle Biopsy of Lung Nodules: Clinical Experience in 1108 Patients

Sang Min Lee, MD, Chang Min Park, MD, Kyung Hee Lee, MD, Young Eun Bahn, MD, Jung Im Kim, MD, Jin Mo Goo, MD

Percutaneous transthoracic needle biopsy (PTNB) is a well-established and commonly used procedure in the work-up of pulmonary nodules, regardless of nodule size (1–3). Although PTNB can be performed with fluoroscopic or ultrasonographic guidance, computed tomography (CT)-guided and CT fluoroscopy–guided PTNB have been widely performed in the diagnosis of small pulmonary nodules (2,3).

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Transcatheter Arterial Embolization as a Treatment for Medial Knee Pain in Patients with Mild to Moderate Osteoarthritis

Yuji Okuno, Amine Mohamed Korchi, Takuma Shinjo, Shojiro Kato

Purpose: Osteoarthritis is a common cause of pain and disability. Mild to moderate knee osteoarthritis that is resistant to nonsurgical options and not severe enough to warrant joint replacement represents a challenge in its management. On the basis of the hypothesis that neovessels and accompanying nerves are possible sources of pain, previous work demonstrated that transcatheter arterial embolization for chronic painful conditions resulted in excellent pain relief. We hypothesized that transcatheter arterial embolization can relieve pain associated with knee osteoarthritis.

AMERICAN JOURNAL OF ROENTGENOLOGY. Local Recurrence After Chemoembolization of Hepatocellular Carcinoma: Uptake of Gadoxetic Acid as a New Prognostic Factor

Hideki Ishimaru, Kazuaki Nakashima, Takayuki Sakugawa, Ayami Sakamoto, Yohjiro Matsuoka, Kazuto Ashizawa and Masataka Uetani

OBJECTIVE. The purpose of this article is to investigate whether there is a difference in susceptibility to transcatheter arterial chemoembolization between hepatocellular carcinomas (HCCs) showing high uptake and those showing low uptake of gadoxetic acid in the hepatobiliary phase of MRI.

AMERICAN JOURNAL OF ROENTGENOLOGY. Ultrasound Findings After Endovascular Stent Deployment in Transplant Liver Hepatic Artery Stenosis

Neil U. Lall, Edward I. Bluth and W. C. Sternbergh III

OBJECTIVE. Endovascular stenting is a safe, effective treatment of hepatic artery stenosis after liver transplant, but no detailed evaluation has been completed of changes in ultrasound monitoring parameters after stenting. This study aims to improve poststenting surveillance by delineating the expected postoperative findings.
