In Hong Kong, 53% of new patients with cancer were aged over 65 years, the incidence of cancer being 8-fold higher than that in younger subjects, and 75% of cancer deaths occur in people aged over 60 years. When cancer is suspected or diagnosed in an elderly person, the doctor faces multiple challenges: diagnostic uncertainty because of multiple pathologies,

Objectives: Volumetric-modulated arc therapy (VMAT) is better than intensity-modulated radiotherapy (IMRT) in terms of its plan qualities and efficiency for the treatment of prostate cancer. It remains unclear whether its use in
Objectives: This study aimed to evaluate the prevalence of brown adipose tissue, as detected by fluorine 18-fluorodeoxyglucose positron emission tomography combined with computed tomography (18F-FDG PETCT), in a Southern Chinese population. It also set out to determine associated factors with brown adipose tissue,

Eosinophilic gastrointestinal disorders are relatively rare disorders characterised by eosinophilic infiltrate
into any layer of the gastrointestinal tract, for example, mucosa, muscularis mucosae, and serosa, usually in
association with peripheral eosinophilia.
Calcium pyrophosphate dihydrate crystal deposition disease of the temporomandibular joint is a rare entity
that has a tendency to mimic bone tumour, leading to unnecessary surgery.
Nodular fasciitis is a rare benign reactive process of the soft tissues, occurring predominantly in the upper
limbs and is less common in the head and neck region.
Objectives: To review the literature and examine the accuracy of clinicians’ prediction of survival as well as prognostic factors determined to be predictive of shorter survival in terminal cancer patients.

Objectives: Neutropenic fever is a serious complication of cytotoxic chemotherapy with significant morbidity
and mortality, for which prompt initiation of antibiotics improves clinical outcomes.
Objective: To describe the pattern of bronchostenosis revealed by computed tomography and virtual
bronchoscopy in patients with active tuberculous endobronchitis and associated pulmonary manifestations.
Objectives: Cone-beam computed tomography (CBCT) in sinonasal imaging is fairly novel and remains limited to
date. This study aimed to compare (1) the image quality of CBCT and multidetector computed tomography (MDCT),
and (2) the eye lens dose for paranasal sinus imaging between these two modes of imaging.
Objective: We aimed to determine whether cerebral cortices have regional variation on diffusion-weighted magnetic resonance imaging (DW-MRI) and corresponding apparent diffusion coefficient (ADC) maps. We also aimed to explore the effect of using 1.5T and 3T MRI with respect to such regional variation.

Objective: To investigate the impact of fractionated stereotactic body radiotherapy (SBRT) on liver function and
identify any dosimetric parameters that may predict deterioration of liver function in patients with hepatitis B
(HBV)–related hepatocellular carcinoma (HCC).

Paediatric spinal pathologies are commonly encountered in clinical practice. This article summarises the normal appearance of lumbar ultrasonography (LUS) and the imaging techniques used to examine the spine in neonates.
Lymphoscintigraphy is useful for assessment of lymphatic leakage after oesophagectomy. This report is of accurate assessment of the site of thoracic lymphatic leakage after oesophagectomy in a 55-year-old patient by using technetium-99m–filtrated sulfur colloid lymphoscintigraphy.
Primary splenic angiosarcoma is an extremely rare solid tumour. Splenic angiosarcoma is a highly aggressive malignancy associated with early metastases and poor prognosis. Most patients present with abdominal pain or a palpable abdominal mass.
Carcinoid tumours occur predominantly in the gastrointestinal tract and bronchial system of the lungs, but they can originate in less common anatomical sites such as the testes, which accounts for <1% of all testicular neoplasms.
This report is of a 75-year-old man with aortoesophageal fistula complicating aortic stent-graft placement for ruptured thoracic aneurysm. The clinical presentation, pathophysiology, imaging features, and treatment options of this condition are discussed.
Meigs̓ syndrome is a rare clinical entity consisting of a triad of ascites, pleural effusion, and benign ovarian tumour. The co-existence of Meigs̓ syndrome and pregnancy is even more infrequent.
We report on a 44-year-old man with nasopharyngeal carcinoma with intracranial extension and leptomeningeal metastases in the spinal cord. Marked resolution of the nasopharyngeal carcinoma and leptomeningeal metastases was achieved
Objective: To review the radiological features of femoral stem loosening of cemented hip arthroplasty on plain
radiographs and to determine their usefulness.
Objective: By auditing paediatric brain computed tomography (CT) performed in four Hong Kong centres, dosage values were obtained to address local practice and suggest improvements.
