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.

Objective: Radiosynoviorthesis has been shown to be effective in decreasing bleeding frequency, reducing pain, and improving quality of life in haemophilic patients.
Objective: We set out to review our unit’s experience in evaluating fetal lung lesions and the accuracy of prenatal diagnosis, and to illustrate the prenatal sonographic and postnatal radiological features of detected lesions.
With the advances that have been made in the field of radiation technology over the past decade, radiotherapy has become a feasible and promising treatment modality for hepatocellular carcinoma.
Although ovarian cancers tend to be fairly chemo-responsive initially, the difficulty facing clinicians is maintaining or prolonging the duration of disease control.
This report describes a 28-year-old woman with stage IV Hodgkin’s lymphoma with nodular sclerosis and bone marrow involvement. The patient received four cycles of adriamycin, bleomycin, vinblastine, and dacarbazine combination chemotherapy
Mature T-cell and natural killer–cell neoplasms can be classified into four categories based on site: cutaneous, extranodal, nodal, and leukaemic. Subtypes within these categories may be aggressive or indolent,
Castleman’s disease is an uncommon lymphoproliferative disorder characterised by hyperplasia of lymphoid tissue. There are three histopathological types of Castleman’s disease: hyaline vascular variant, plasma cell variant, and mixed cellularity.
Biopharmaceuticals or biologics were first introduced at the beginning of the 1980s and are now well established in the treatment of a wide variety of diseases. Biosimilars are biopharmaceuticals that are similar, but not identical,
Palliative chemotherapy and / or radiotherapy continue to represent the standard of care for patients with inoperable, advanced-stage non–small-cell lung cancer.
Angiogenesis is essential for tumour growth and metastasis, and constitutes an important process in the control of cancer progression. The use of anti-angiogenic agents, particularly those targeting vascular endothelial growth factor,
The human epidermal growth factor receptor HER2/neu gene is amplified and overexpressed in 25 to 30% of breast cancers. In women with HER2-positive advanced or metastatic breast cancer,
Mortality from metastatic colorectal cancer has declined over the past decade, partly due to improvement in survival secondary to incorporation of targeted biologics in the treatment paradigm.
With the recent advancement of molecular targeting therapy, we are witnessing a paradigm shift in the role of pathology laboratories in the management of solid tumours.
The treatment of rectal cancer is evolving and it nicely demonstrates the beauty of multimodality treatment. Unlike total mesorectal excision in surgery, which has probably marked the climax in the advancement of surgical treatment of rectal cancer,
The high prevalence of chronic hepatitis B virus infection in Hong Kong makes hepatocellular carcinoma one of the area’s most important solid tumours. Late presentation and underlying cirrhosis mean that many hepatocellular carcinomas are inoperable at first presentation.
