An Anatomy-aware Framework for Automatic Segmentation of Parotid Tumor from Multimodal MRI [PDF]
Magnetic Resonance Imaging (MRI) plays an important role in diagnosing the parotid tumor, where accurate segmentation of tumors is highly desired for determining appropriate treatment plans and avoiding unnecessary surgery. However, the task remains nontrivial and challenging due to ambiguous boundaries and various sizes of the tumor, as well as the ...

Deep lobe parotid gland pleomorphic adenoma involving the parapharyngeal space
Pleomorphic adenomas are slow growing, well-demarcated benign neoplasms that constitute more than 80% of benign parotid tumours. Deep lobe parotid pleomorphic adenomas are rare tumors that present a diagnostic and therapeutic challenge.

Evaluation of [18F]PSMA-1007 uptake variability in patients with prostate cancer. [PDF]
Abstract Background The biodistribution of PSMA‐ligands is of interest in radionuclide therapy planning. We investigated the variability of [18F]PSMA‐1007 uptake in organs at risk and in relation to tumour burden in prostate cancer patients. Methods A total of 1086 patients who underwent PSMA PET‐CT for staging or recurrence of prostate cancer were ...

Malignant Mucoepidermoid Tumor Arising in the Accessory Parotid Gland: A Case Report
Purpose: The head and neck surgeon’s fascination with parotid surgery arises from the gland’s spectrum of histopathological presentations, as well as the diversity of its morphological features.

Parotid Gland MRI Segmentation Based on Swin-Unet and Multimodal Images [PDF]
Background and objective: Parotid gland tumors account for approximately 2% to 10% of head and neck tumors. Preoperative tumor localization, differential diagnosis, and subsequent selection of appropriate treatment for parotid gland tumors are critical.

Negative-contrast neurography: Imaging the extracranial facial nerve and its branches using contrast-enhanced variable flip angle turbo spin echo MRI [PDF]
Background and Purpose: Various 'positive-contrast' neurographic methods have been investigated for imaging the extracranial course of the facial nerve. However, nerve visibility can be inconsistent with these sequences and may depend on the composition of the parotid gland, limiting consistent identification.

Computational Intelligence Approach to Improve the Classification Accuracy of Brain Neoplasm in MRI Data [PDF]
Automatic detection of brain neoplasm in Magnetic Resonance Imaging (MRI) is gaining importance in many medical diagnostic applications. This report presents two improvements for brain neoplasm detection in MRI data: an advanced preprocessing technique is proposed to improve the area of interest in MRI data and a hybrid technique using Convolutional ...
