Multislice Spiral Computed Tomography in Cardiac Imaging

C Hong, C Becker, R Bruening, MF Reiser

Hong Kong J Radiol 2001;4:252-8

Objective: Multislice computed tomography is an emerging technology with the potential for non-invasive coronary investigation. The aim of this study was to evaluate the feasibility and limitations of multislice computed tomography in the detection of coronary artery disease.

Patients and Methods:

Comparison of Magnetic Resonance Spectroscopic Imaging and Single Voxel Magnetic Resonance Spectroscopy for Suspected Recurrent Brain Tumour or Radiation Necrosis

YL Chan, H Schlemmer, DKW Yeung, T Wilhelm, P Bachert

Hong Kong J Radiol 2001;4:259-63

Objective: To qualitatively and quantitatively compare spectra obtained on single voxel spectroscopy and magnetic resonance spectroscopic imaging in suspected recurrence of brain tumour or radiation necrosis.

Patients and Methods: Six patients with suspected recurrence of brain tumour or radiation necrosis

Viewing Conditions in Diagnostic Imaging: A Survey of Selected Malaysian Hospitals

S Lau, KH Ng, BJJ Abdullah

Hong Kong J Radiol 2001;4:264-7

Objectives: To assess the appropriateness of viewbox and display monitor luminance and radiology reading room illumination in selected Malaysian hospitals.

Materials and Methods: The luminance of viewboxes was measured in 4 hospitals, along with the display monitors in 1 of

Magnetic Resonance Imaging Evaluation of the Clivus and Nasopharyngeal Carcinoma

KT Wong, YL Chan, C Metreweli

Hong Kong J Radiol 2001;4:268-71

Objectives: To establish the age-related distribution of clival marrow magnetic resonance imaging appearances in ethnic Chinese and to compare these findings with the clival marrow magnetic resonance imaging appearances seen in Chinese patients with nasopharyngeal carcinoma.

Materials and Methods: T1-weighted


A New Method for Fixation of Drainage Catheters

BJJ Abdullah

Hong Kong J Radiol 2001;4:272-3

This technical note reports on a new method of anchoring drainage catheters developed at the University of Malaya Medical Centre, based on the use of cable ties. This method can be implemented at a fraction of the cost of commercial


Fracture of the Costal Cartilage: Computed Tomography Assists Diagnosis

WC Torreggiani, ID Lyburn, F Thornton, MJ Lee

Hong Kong J Radiol 2001;4:274-6

Rib fractures are common and almost always involve the osseous component of a rib. They are typically diagnosed on plain film. Fractures of the costal cartilage are rare and are invisible on plain film. We describe a case in which

Radiological Features of Isolated Unilateral Absence of the Pulmonary Artery

MWC Yiu, DV Le, Y Leung, CGC Ooi

Hong Kong J Radiol 2001;4:277-80

We report a case of isolated unilateral absence of the pulmonary artery, a rare congenital anomaly, in a woman with exertional dyspnoea. The chest radiograph appearances of this anomaly are often mistaken for other conditions, such as Swyer-James-MacLeod’s syndrome or

Cervicothoracic Intradural Lipoma: Features on Magnetic Resonance Imaging


Hong Kong J Radiol 2001;4:281-3

Intraspinal intradural lipomas are rare congenital tumours. This case report describes a patient with an intramedullary cervicothoracic lipoma, demonstrated on magnetic resonance imaging and treated by subtotal resection and laminectomy. The clinical and pathological features of the case are discussed.

Parosteal Osteosarcoma Arising from a Rib: Imaging Features with an Emphasis on Magnetic Resonance Imaging

WC Torreggiani, DW Struk, K Al-Ismail, PL Munk, K Evans, JX O’Connell

Hong Kong J Radiol 2001;4:284-7

Parosteal osteosarcomas are uncommon neoplasms that typically affect the long bones. Primary involvement of a rib is very rare. The imaging features of a parosteal osteosarcoma involving a rib are described, including the magnetic resonance imaging features, which have not

Neonatal Total Parenteral Nutrition Ascites Secondary to Umbilical Venous Catheterisation

JYH Hui, KKL Lo, J Lo, MLM Chan, JCS Chan

Hong Kong J Radiol 2001;4:288-90

Two cases of hepatic perforation with total parenteral nutrition ascites and hepatic calcification, are reported. Hepatic perforation is a rare complication of umbilical venous catheterisation, resulting in intraperitoneal extravasation of the total parenteral nutrition fluid.

Appendiceal Diverticulosis in a Chinese Patient

MYF Wong , WK Chau

Hong Kong J Radiol 2001;4:291-3

Appendiceal diverticulosis is a rare entity. An inflamed appendix has a higher perforation rate if associated with diverticulitis. Barium enema and computed tomography are useful in demonstrating this lesion and its associated complications. This article describes the radiographic findings in a

Arterio-portal Fistula Following Recent Liver Biopsy

WK Kan, KY Lau, WT Fung, KH Fung

Hong Kong J Radiol 2001;4:294-6

Arterio-portal fistula may develop at the biopsy site after percutaneous liver biopsy and demonstrates a characteristic appearance on angiography and Lipiodol computed tomography scan of the liver performed shortly after the biopsy. Radiologists should be familiar with these findings in

Coexistence of Malignant Meningioma and Anaplastic Ganglioglioma

HL Chau, CM Chan, WM Pong, TC Tan, JY Cheung, SC Chan

Hong Kong J Radiol 2001;4:297-306

The case of a 45-year-old Chinese man with coexisting intracranial tumours is reported. Following presentation with left hemiparesis, computed tomography and magnetic resonance imaging of the patient’s brain identified a large, soft tissue mass, with massive oedema in the adjacent
