Percutaneous Sclerotherapy for Low-flow Vascular Malformations in Paediatric Patients: 6-Year Experience of a Multidisciplinary Team

Full Article

ACW Lee, HS Fung, WL Poon, PCM Chan, MWY Leung, CSW Liu, D Luk, WY Cheung, KL Yuen, D Tang, PC Kwok, KW Tang

Hong Kong J Radiol 2018;21:16-24

DOI: 10.12809/hkjr1616441

Objectives: The Vascular Anomalies Multidisciplinary Team at the Queen Elizabeth Hospital, Hong Kong, delivers one-stop integrated care by a comprehensive team of specialists and nurses to paediatric patients with vascular anomalies. This study aimed to review the efficacy, safety, and outcomes of percutaneous sclerotherapy performed at our centre for low-flow vascular malformations in paediatric patients.

Hong Kong J Radiol 2018;21:25-33

DOI: 10.12809/hkjr1616821

Objective: To review the imaging features of mucinous carcinoma of the breast, a rare subtype of ductal carcinoma of the breast.

Magnetic Resonance Imaging to Predict Neurological Outcome in Children with Acute Encephalitis

Full Article

GCY Chan, TW Yeung, YC Wong

Hong Kong J Radiol 2018;21:34-9

DOI: 10.12809/hkjr1616415

Objective: To identify magnetic resonance imaging (MRI) variables that are predictive of neurological outcome in children with acute encephalitis.

High-pitch Dual-source Computed Tomography Coupled with Sinogram-affirmed Iterative Reconstruction: Image Quality and Radiation Dose in Children

Full Article

JCY Lee, KS Tse, HY Lau, WS Fok, KK Chan, WH Chat, WK Yung, TM Mui

Hong Kong J Radiol 2018;21:40-7

DOI: 10.12809/hkjr1616427

Objectives: High-pitch imaging in computed tomography (CT) reduces scan time and radiation dose at the expense of increased noise. Recent advances in iterative reconstruction techniques allow for noise reduction without a significant increase in processing time, by using Sinogram-Affirmed Iterative Reconstruction (SAFIRE). We evaluated the combined effects of high-pitch imaging with SAFIRE in CT of the thorax and abdomen on image quality, diagnostic confidence, and radiation dose in children.

Incidence and Clinical Impact of Focal Pituitary Uptake in 18F-Fluorodeoxyglucose Positron-emission Tomography–Computed Tomography: 5-Year Retrospective Review

Full Article

KK Wu, BT Kung, TK Au Yong

Hong Kong J Radiol 2018;21:48-53

DOI: 10.12809/hkjr1616832

Objectives: To identify the incidence and clinical significance of incidental pituitary uptake in whole-body positron-emission tomography–computed tomography using 18F-fluoro-2-deoxy-d-glucose (18F-FDG PET-CT) in Hong Kong.


Non-traumatic Ischiorectal Epidermoid Cyst

Full Article

GKY Lee, KH Lee, CY Chu, HL Li, JLS Khoo

Hong Kong J Radiol 2018;21:54-7

DOI: 10.12809/hkjr1616403

Epidermoid cysts in the pelvis are rare and usually associated with local trauma or surgery. They may mimic more threatening lesions and develop complications when they become large. We report a case of epidermoid cyst arising from the ischiorectal fossa in a woman with no history of local trauma or surgery.

Full Article

HJ Baek, K Bae, KN Jeon, DS Choi, HS Shin, KH Lee

Hong Kong J Radiol 2018;21:58-64

DOI: 10.12809/hkjr1616412

Alcohol has direct and indirect toxic effects on the brain, such as oxidative metabolism, inflammatory reactions, and DNA damage.

Hong Kong J Radiol 2018;21:65-71

DOI: 10.12809/hkjr1616816

Encapsulated papillary carcinoma or intracystic papillary carcinoma of the breast is a rare tumour and is a special subtype of carcinoma.


Positron-emission Tomography–Computed Tomography for Detection of Primary Pericardial Lymphoma

Full Article

JCY Lee, KH Tsang, W Cheuk, MK Chan

Hong Kong J Radiol 2018;21:e1-7

DOI: 10.12809/hkjr1616405

Primary pericardial lymphoma is rare in immunocompetent patients. Its symptoms are non-specific and may lead to a delayed diagnosis.
