Re-evaluating Endometrial Thickness in Symptomatic Postmenopausal Patients for Excluding Cancer: Systematic Review and Meta-Analysis.

Purpose: The current ACR and American College of Obstetricians and Gynecologists guidelines recommend a ≤4-mm endometrial thickness threshold for excluding endometrial cancer in symptomatic postmenopausal patients. This systematic review and meta-analysis aims to re-evaluate the optimal endometrial thickness threshold on imaging for excluding cancer in symptomatic postmenopausal patients.

Materials And Methods: A systematic search of MEDLINE, EMBASE, Cochrane Library, and Scopus from inception to October 2023 was performed in addition to a gray literature search.

Abbreviated Multiparametric MR Solution (the "Liver Triple Screen"), the Future of Non-Invasive MR Quantification of Liver Fat, Iron, and Fibrosis.

To review the findings of a multiparametric MRI (the "liver triple screen") solution for the non-invasive assessment of liver fat, iron, and fibrosis in patients with chronic liver disease (CLD). A retrospective evaluation of all consecutive triple screen MRI cases was performed at our institution over the last 32 months. Relevant clinical, laboratory, and radiologic data were analyzed using descriptive statistics.

Ovarian vein syndrome - Rare ovarian vein compression of the ureter.

Ovarian vein syndrome is a rare condition involving the compression of the ureter by the ovarian vein. Since it was first described, very few cases have been reported in literature. We present a case of a 37-year-old female with typical symptoms and common right-side involvement.

Vascular compression syndromes in the abdomen and pelvis: a concise pictorial review.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management.

Mechanical Unloading of Engineered Human Meniscus Models Under Simulated Microgravity: A Transcriptomic Study.

Osteoarthritis (OA) primarily affects mechanical load-bearing joints, with the knee being the most common. The prevalence, burden and severity of knee osteoarthritis (KOA) are disproportionately higher in females, but hormonal differences alone do not explain the disproportionate incidence of KOA in females. Mechanical unloading by spaceflight microgravity has been implicated in OA development in cartilaginous tissues.

In vivo photoacoustic difference-spectra imaging of bacteria using photoswitchable chromoproteins.

Photoacoustic (PA) imaging offers great promise for deep molecular imaging of optical reporters but has difficulties in imaging multiple molecular probes simultaneously in a strong blood background. Photoswitchable chromoproteins like BphP1 have recently allowed for sensitive PA detection by reducing high-blood background signals but lack multiplexing capabilities. We propose a method known as difference-spectra demixing for multiplexing multiple photoswitchable chromoproteins and introduce a second photoswitchable chromoprotein, sGPC2.

Sparsity-based reconstruction for super-resolved limited-view photoacoustic computed tomography deep in a scattering medium.

Delay-and-sum beamforming (DSB) of photoacoustic data does not incorporate a priori spatial sparsity of the imaging target. By incorporating this information into beamforming for limited-view photoacoustic computed tomography, we experimentally obtained enhanced resolution images of wires at a depth of 8.5 mm in a tissue mimicking scattering medium.

Multifrequency Interlaced CMUTs for Photoacoustic Imaging.

Multifrequency capacitive micromachined ultrasound transducers (CMUTs) are introduced consisting of interlaced 82- [Formula: see text] (low frequency) and 36- [Formula: see text] (high frequency) membranes. The membranes have been interlaced on a scale smaller than the shortest wavelength of operation allowing several advantages over other multifrequency transducer designs including aligned beam profiles, optimal imaging resolution, and minimal grating lobes. The low- and high-frequency CMUTs operate at 1.

Feasibility of modulation-encoded TOBE CMUTS for real-time 3-D imaging.

Modulation-encoded top orthogonal to bottom electrode (TOBE) capacitive micromachined ultrasound transducers (CMUTs) are proposed 2-D ultrasound transducer arrays that could allow 3-D images to be acquired in a single acquisition using only N channels for an N × N array. In the proposed modulation-encoding scheme, columns are not only biased, but also modulated with a different frequency for each column. The modulation frequencies are higher than the passband of the CMUT membranes and mix nonlinearly in CMUT cells with acoustic signals to produce acoustic signal sidebands around the modulation carriers in the frequency domain.

Mosaic acquisition and processing for optical-resolution photoacoustic microscopy.

In optical-resolution photo-acoustic microscopy (OR-PAM), data acquisition time is limited by both laser pulse repetition rate (PRR) and scanning speed. Optical-scanning offers high speed, but limited, field of view determined by ultrasound transducer sensitivity. In this paper, we propose a hybrid optical and mechanical-scanning OR-PAM system with mosaic data acquisition and processing.
