Imaging of Muscle Injuries

LLS Wong

Hong Kong J Radiol 2005;8:191-201

Muscle injuries are common, particularly in sports medicine. Muscle injuries comprise those due to indirect trauma, including delayed onset muscle soreness and muscle strains, and those due to direct trauma, including muscle laceration and contusion. This illustrated review article demonstrates

Objective: To assess the appropriateness and outcomes of computed tomography brain scanning for headaches in a paediatric population.

Materials and Methods: Medical records and radiological reports for all computed tomography brain scans performed on paediatric patients aged 18 years or younger

Swallowing Function after Altered Fractionation Radiotherapy for Head and Neck Carcinoma

KH Yu, M Chua, AC Vlantis, MKM Kam, WY Lee, RKY Tsang, HY Yuen, EP Hui, ATC Chan

Hong Kong J Radiol 2005;8:207-13

Objective: To investigate swallowing function outcome in patients with head and neck cancer who received altered fractionation radiotherapy.

Patients and Methods: Forty nine patients with bulky T2 tumours or American Joint Committee on Cancer stage III/IV disease were treated with

Reliability of Quantitative Assessment of Hepatic Steatosis on Breath-hold Dual Echo In-phase and Opposed-phase Gradient-echo MRI

SF Lee, YL Chan, B Tomlinson, S Ho, NWY Leung, BSP Fok

Hong Kong J Radiol 2005;8:214-7

Objective: To assess the reliability of quantitative measurement of signal intensity change in the liver on breath-hold gradient echo in-phase and opposed-phase imaging in hepatic steatosis.

Patients and Methods: The study population comprised 19 subjects with previous sonographic diagnosis of

Use of Small Bore Tubes for Treatment of Malignant Pleural Effusions in a Palliative Care Centre

EKC Lee, KK Yuen, WK Sze, OC Li, MK Yuen

Hong Kong J Radiol 2005;8:218-21

Objective: To evaluate the outcome of malignant pleural effusion drainage using small bore catheters.

Patients and Methods: This retrospective study was conducted at the Palliative Care Centre at Tuen Mun Hospital, a regional hospital in Hong Kong. Patients with malignant

KW Yang, WH Luk, DHY Cho, TKL Loke, JCS Chan

Hong Kong J Radiol 2005;8:222-5

Objective: To compare the clinical response and outcome for direct gallbladder puncture and transhepatic puncture techniques in ultrasound-guided percutaneous cholecystostomy for critically ill and non-surgically fit patients with acute calculous cholecystitis.

Patients and Methods: Twenty seven consecutive critically ill and high

Cardiac Output and Index in Obese and Non-obese Patients using Gated Single Photon Emission Computed Tomography Sestamibi Perfusion Imaging

JP Coffey, JC Hill

Hong Kong J Radiol 2005;8:226-32

Objective: To assess prospectively the overall prevalence of abnormal cardiac index values in a symptomatic group of patients from gated single photon emission computed tomography perfusion studies and to compare cardiac index of patients with body mass index <30 and

Volumetric High-resolution Computed Tomography of the Lung—a Comparison to Standard Acquisition in Diffuse Lung Disease

JJ Kasthoori, G Kumar, ML Wastie

Hong Kong J Radiol 2005;8:233-43

Aim: The purpose of this study was to compare volumetric high-resolution computed tomography of the lungs, which can be reconstructed in different planes and subjected to various post-processing techniques, to standard high-resolution computed tomography of the lungs.

Patients and Methods: Sixty

Comparison of Superparamagnetic Iron Oxide-enhanced Magnetic Resonance Imaging and 5-Phase Computed Tomography in the Detection and Characterisation of Focal Liver Lesions

SSM Lo, KW Siu, TK Tsang, KY Kwok, AMW Wai, HS Fung, FCY Lam, SCH Chan

Hong Kong J Radiol 2005;8:254-5

Foreign body ingestion is not uncommon but the majority of foreign objects ingested traverse the gastrointestinal tract without complications. We report a case of retroperitoneal abscess in a 38-year-old man following perforation of the colon by an ingested toothpick.


Wide-volume Partial Breast Interstitial Brachytherapy Alone after Lumpectomy in Breast-conserving Treatment for Early Breast Cancer

RKY Wong, RKC Ngan, F Tang

Hong Kong J Radiol 2005;8:256-60

As most local recurrence after breast-conserving treatment occurs within 2 cm around the lumpectomy cavity, wide-volume partial breast rather than whole breast irradiation has been actively investigated with a view to decreasing radiation toxicities. Replacing external beam radiotherapy by wide-volume
