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...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...
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....
Identifying clinically useful salivary substitutes
This in vitro study analysed the efficacy of salivary substitutes used in the treatment of xerostomia following head neck irradiation. The researchers applied the products under evaluation onto a synthetic surface and onto cellular gingival models. The products were then...
Margin control using optical techniques in head and neck surgery
Emerging optical techniques such as high-resolution microendoscopy (HRME) are currently being examined for their reliability in discriminating benign from neoplastic epithelium. These techniques may offer the potential to detect the margin of an upper aerodigestive tract tumour in a non-invasive...The effects of hormonal changes across menstrual cycle on high frequency auditory thresholds
Physiological changes during the menstrual cycle are well documented; do these changes extend to the auditory system? Lalsa Shilpa Perepa and Rewa Indurkar delve into the literature to find the evidence. Menstrual cycle refers to a series of changes that...
Which scan for children with bilateral sensorineural hearing loss? Keeping the debate going…
There have been years of debate about the appropriate imaging strategy for children with bilateral sensorineural hearing loss. For those children undergoing cochlear implant surgery, CT may provide some assistance to surgical planning, although this is not necessary in children...
Predictors of complications in patients undergoing oral cavity cancer surgery
Surgical management of oral cavity cancers is complex, frequently involving extensive resections and complicated reconstructions. Quantification of risk in an individual patient may allow surgeons to more effectively identify patients at higher risk of complications and develop strategies for prevention,...
Hearing protectors and speech perception
This study tested 31 subjects using hearing protectors by maintaining a constant intensity level for the speech signal while varying background noise levels. The goal was to use this test to detect speech perceptual abilities under different hearing protectors –...
