OBJECTIVE: The purpose was to evaluate the presence of gas in the tissue adjacent to the laryngeal structures, "the gas bubble sign", in cases of hanging as a diagnostic indicator of neck trauma. METHODS: In this study, postmortem computed tomography scans and autopsies of 35 victims of hanging were examined to reveal age-dependent changes, laryngeal fracture, fracture location, and the presence of gas. A matched group with cardiac arrest or intoxication was used as controls (n = 35)...

Renal angiomyolipoma (AML) is an uncommon renal tumour, generally composed of mature adipose tissue, dysmorphic blood vessels, and smooth muscle. Identification of intratumoural fat on unenhanced CT images (UECT) is the most reliable finding for establishing the diagnosis of renal AML. However, AMLs sometimes exhibit atypical findings, including cystic as well as solid forms; some of these variants overlap with the appearance of other renal tumours. A rare type of AML, the epithelioid type, possesses malignant potential...

OBJECTIVE: At our tertiary cardiothoracic centre cardiac MRI and thoracic CT scans are performed in patients with implanted LINQ devices. The degree of foreign body artefact associated with the LINQ device, and its clinical importance, has not previously been assessed. A case series review was therefore performed with a simultaneous review of patient safety and data loss events, secondary to the MRI environment. METHODS: A local database search identified LINQ device patients who underwent thoracic CT or cardiac MRI scans between March 2014 and December 2016...

Primary extra nodal lymphomatous involvement of the genitourinary tract is rare and secondary extra-nodal involvement in disseminated disease occurs more frequently. Imaging of metabolic activity with 2-[fluorine-18] fluoro-2-deoxy-d-glucose (FDG) used in positron emission tomography (PET) facilitates the identification of these extra-nodal sites of disease, particularly in the absence of structural lesions on conventional imaging modalities. Primary extra-nodal lymphoma affecting the genitourinary system is often caused by high-grade Non-Hodgkin's Lymphoma (NHL) with the most common subtype being Diffuse Large B-Cell Lymphoma (DLBCL)...

Research over recent years has demonstrated that curative external beam radiotherapy can be safely and efficaciously delivered with roughly half the number of treatments which was previously considered standard. We review the data supporting this change in practice, methods for implementation, as well as emerging future directions.

OBJECTIVE: Hyperintense area on T1-weighted images (T1 HIA) have been reported as suggestive features of uterine leiomyosarcoma (LMS), but differentiating LMS from leiomyoma (LM) is often difficult. This study aimed to evaluate the differences between uterine LMS and LM demonstrating intratumoral T1 HIA. METHODS: MR imaging was performed in 509 patients with 1,137 uterine smooth muscle tumors [14 LMSs, five smooth muscle tumors of uncertain malignant potential (STUMPs), and 1,118 LMs] which exceeded 3 cm in diameter...

OBJECTIVE: To evaluate the test-retest reliability of repeated in-bore MRI-guided prostate biopsy (MRGB). METHODS: Nineteen lesions in 7 patients who had consecutive MRGBs were retrospectively analyzed. Three patients had only 2 consecutive MRGBs and two patients had 3 consecutive MRGBs. Both multiparametric MRI and MRGBs were performed using a 3T MRI scanner. Pathology results were categorized into benign, suspicious and malignant. Consistency between 1st and subsequent biopsy results were analyzed as well as the negative predictive value (NPV) for prostate cancer...

Deep-seated, low grade lipomatous lesions detected on imaging often cause uncertainty for diagnosis and treatment. Confidently distinguishing lipomas from well-differentiated liposarcomas (WDL) is often not possible on imaging. The approach to management of such lesions varies widely between institutions. Applying an evidenced-based approach set around published literature that clearly highlights how criteria such as lesion size, location, age and imaging features can be used to predict the risk of WDL and subsequent de-differentiation would seem sensible...

Anterior knee pain in active young adults is commonly related to patellofemoral (PF) pain syndrome (PFPS), which can be broadly classified into patellar malalignment and patellar maltracking. PFPS can be caused by a host of miserable malalignments, such as excessive femoral antetorsion, tibial varus / external rotation, knee valgus and pes planus. Radiographic, CT and MRI evaluations are commonly obtained to further elucidate the malalignment and maltracking abnormalities and exclude other related differentials, such as lateral meniscus tear, extensor tendon tear, anterior tenosynovial giant cell tumor and plica syndrome...

OBJECTIVE: 18F-Fluciclovine (FACBC) is an amino acid PET radiotracer approved for recurrent prostate cancer imaging. We investigate the use of Bayesian penalised likelihood (BPL) reconstruction for 18F-fluciclovine PET. METHODS: Fifteen 18F-fluciclovine scans were reconstructed using OSEM, OSEM+point spread function modeling (PSF) and BPL using β values 100-600. Lesion SUVmax, organ SUVmean and standard deviation were measured. De-identified reconstructions (OSEM, PSF, BPL using β200-600) from 10 cases were visually analysed by two readers who indicated their most and least preferred reconstructions, and scored overall image quality (IQ), noise level, background marrow IQ and lesion conspicuity...

Peter Wardman
Nitroimidazoles have been extensively explored as hypoxic cell radiosensitizers but have had limited clinical success, with efficacy restricted by toxicity. However, they have proven clinically useful as probes for tumour hypoxia. Both applications, and probably much of the dose-limiting toxicities, reflect the dominant chemical property of electron affinity or ease of reduction, associated with the nitro substituent in an aromatic structure. This single dominant property affords unusual, indeed extraordinary flexibility in drug or probe design, suggesting further development is possible in spite of earlier limitations, in particular building on the benefit of hindsight and an appreciation of errors made in earlier studies...

OBJECTIVE: Magnetic resonance imaging (MRI) is being used increasingly as a modality than can provide important information about breast cancer. Diffusion weighted imaging (DWI) is an imaging technique from which ADC values can be calculated in addition to obtaining important structural information which cannot be obtained from other imaging studies. We did not find any significant relationships between ADC values and prognostic factors, but did provide some explanations for conflicting results in the literature...
