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,...

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...

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...

Choline PET-CT: an accurate diagnostic tool for the detection of parathyroid adenoma?

Hyperparathyroidism (HPT) is an endocrine disorder characterised by an increase in the secretion of parathyroid hormone (PTH), with a resulting increase in calcium plasma levels, which can cause renal lithiasis, fractures, and osteoporosis, the most frequent symptoms of the disease....

Preoperative CT checklist (using the ‘CLOSE’ mnemonic) improves identification of anatomical variants for endoscopic sinus surgery

Computed tomography (CT) scans of the paranasal sinuses act as roadmaps for endoscopic sinus surgery (ESS) and careful inspection preoperatively warns the operating surgeon of critical anatomical variants. This study aimed to investigate if implementation of a pre-ESS CT checklist...

CT and intraoperative nerve monitoring to identify non-recurrent laryngeal nerve during thyroid surgery

A non-recurrent laryngeal nerve (NRLN) is a rare (incidence 0.3% to 1.3%) anatomical variant that results in a higher rate of vocal cord palsy following thyroid surgery. This team from China examined the utility of preoperative CT and intraoperative nerve...
