Natera Ovarian Cancer Detection Assay

The purpose of this study is to collect blood, tissue, and health information from individuals with adnexal masses to develop a blood test to detect ovarian cancer.

Prospective Validation and Comparison of Different Ultrasound Methods for Discrimination Between Benign and Malignant Ovarian/Tubal Masses Prior to Surgery

The ability of different methods to discriminate between benign and malignant adnexal masses has been compared in a meta-analysis showing that the IOTA Simple Rules and the IOTA logistic r...

Diffusion MRI (Magnetic Resonance Imaging) Using ADC (Apparent Diffusion Coefficient) Histograms in the Evaluation of Adnexal Tumor Aggressiveness

Diffusion-weighted sequences have been routinely performed for years to study the pelvis. They have been so far mainly qualitatively interpreted, that is to say as the absence or presence ...

Contrast-Enhanced Subharmonic Ultrasound Imaging in Improving Characterization of Adnexal Masses in Patients Undergoing Surgery

This pilot clinical trial studies how well contrast-enhanced subharmonic ultrasound imaging works in improving the characterization of adnexal masses in patients undergoing surgery. Contra...

Risk of Malignancy Index and Assiut Scoring Model for Adnexal Malignancy

The presence of an adnexal mass is a frequent reason for a woman to be referred to a gynaecologist. The discrimination between benign and malignant adnexal masses is central to decisions r...

Ocular Adnexal Amyloidosis: A Mass Spectrometric Analysis.

Ocular adnexal amyloidosis may represent localized manifestation of an underlying systemic process. Accurate identification of the amyloid fibrils can guide the systemic work up and treatment. The aim...

Sigmoid Colon Perforation Mimics a Tuboovarian Absces.

An adnexal mass may be diagnosed after a routine pelvic ultrasonographic examination or an emergent hospital admission due to rupture of ectopic pregnancy, adnexal torsion or rupture of tuboovarian ab...

Elevated serum CA 19-9 with adnexal mass: is it always an ovarian malignancy?

Endometriotic cysts a common benign gynaecological disease in women of reproductive age. We report an unusual case of ruptured endometrioma associated with increased CA 19-9. A 27-year-old woman prese...

A positive urine pregnancy test (UPT) with adnexal mass; ectopic pregnancy is not the ultimate diagnosis.

A positive urine pregnancy test (UPT) with adnexal mass in ectopic pregnancy is not the ultimate diagnosis. The incidence of ectopic pregnancy is about 27 per 1000 pregnancies [1]. On average, about 6...

Magnetic resonance imaging of pediatric adnexal masses and mimics.

Evaluation of adnexal masses in children and adolescents relies on imaging for appropriate diagnosis and management. Pelvic MRI is indicated and adds value for all adnexal masses when surgery is consi...

Medical and Biotech [MESH] Definitions

A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.

An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.

A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.

A benign adnexal neoplasm composed of EPITHELIAL CELLS. They typically manifest as solitary papules and occur only in the skin.

A mass-spectrometric technique that is used for microscopic chemical analysis. A beam of primary ions with an energy of 5-20 kiloelectronvolts (keV) bombards a small spot on the surface of the sample under ultra-high vacuum conditions. Positive and negative secondary ions sputtered from the surface are analyzed in a mass spectrometer in regards to their mass-to-charge ratio. Digital imaging can be generated from the secondary ion beams and their intensity can be measured. Ionic images can be correlated with images from light or other microscopy providing useful tools in the study of molecular and drug actions.
