Head and neck cancer and PET-CT

Positron emission tomography-computed tomography (PET-CT) is an imaging technique in which abnormalities of tissue metabolism are precisely superimposed onto the anatomy. It relies on the premise that malignant cells are more metabolically active compared with non-malignant cells. On this basis,...

PET-CT for malignant nasopharyngeal lesions

This retrospective Turkish review of 92 patients aimed to determine the ability of fluorine 18-fluorodeoxyglucose (FDG) maximum standardised uptake value (SUVmax) on positron emission tomography/computerised tomography (PET/CT) to differentiate benign processes and malignant nasopharyngeal lesions. The authors retrospectively reviewed the...

What to do with incidental findings on FDG PET/CT?

18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG PET/CT) is commonly used in head and neck cancer staging. This investigation frequently identifies incidental findings unrelated to the index head and neck cancer. To assess the nature of these incidental findings, notes of...

CT chest surveillance for oral cancer patients

Computed tomography (CT) imaging of the chest is performed as part of the assessment of patients with oral cancer to exclude pulmonary metastasis or synchronous cancer. This process is integral to staging of the disease. In some cases, non-specific pulmonary...

Accuracy of CT scans for cholesteatoma and its complications

Chronic ear disease with cholesteatoma generally requires active surgical management and the requirement for this needs precise assessment. A retrospective study was conducted to evaluate the accuracy of CT scan findings in terms of predicting cholesteatoma and its associated complications...

CT guided cochlear implant programming improves performance

There is currently no national (UK) consensus on imaging patients for cochlear implantation. This paper may change that. It has shown increased hearing and quality of life in paediatric cochlear implant (CI) users when the programming has been assisted by...

Back to basics: nasendoscopy beats CT, again!

There are few otolaryngologists (or patients) who have not been confronted with a computed tomography scan referring to a deviated septum. In a very similar way to the accidental findings of sinus mucosal thickening, the clinician is left in a...

XORAN Mobile and Fixed CT

We are proud to offer intraoperative and OPD CBCT scanners from Xoran Technologies. The low-dose radiation, cone beam CT scanner systems are specifically designed for diagnosis of the patient at point-of-care. The MiniCAT IQ and xCAT solutions are compact and...

KALORIstar CT – with ACT

Active cooling technology (ACT) guarantees a cold stimulus down to 7 °C below ambient temperature. The KALORIstar CT air irrigator is easy to use and ready for remote control by eVNG USB system – true one-button-operation. 20 °C … 50...

CT-scan instead of rigid bronchoscopy in paediatric foreign body aspiration?

Many centres would still use rigid bronchoscopy as the gold standard for possible foreign body aspiration (FBA) in children. Evidence is growing that CT scanning in these situations is a reliable alternative, especially as rigid bronchoscopy (RB) still carries a...

Best timing for post-treatment PET-CT scans in head and neck cancer

Unfortunately we know that the recurrence rate for head and neck cancer can be high, up to 30-50% in some series. These recurrences tend to occur within the first two years following treatment. Optimal surveillance strategies to detect recurrences early...

Not as rare as we think? Silent sinus syndrome incidence on CT heads

It is relatively uncommon to come across a case of silent sinus syndrome (SSS), but not as rare as the prevalence in the literature might suggest – the authors of this study note that only 100 cases are reported in...
