Imaging Studies IV: Magnetic Resonance Imaging

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Ovaries

Ovaries

The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.
On the ovarian surface, a layer of cuboidal...

Summary

Prenatal magnetic resonance imaging (MRI) effectively visualizes fetal ovarian cysts, often confirming ultrasonography (US) findings. In some cases, MRI provides additional diagnostic details for improved perinatal care.

Fetal Medicine
Gynecologic Oncology

Background:

Fetal ovarian cysts are common intra-abdominal masses in female fetuses.
These cysts may necessitate perinatal intervention.
Ultrasonography (US) is the standard diagnostic tool.

Purpose of the Study:

To evaluate the utility of prenatal magnetic resonance imaging (MRI) in visualizing fetal ovarian cysts.
To assess MRI's role as an adjunct to US in prenatal diagnosis of ovarian cysts.

Main Methods:

Retrospective review of 17 fetal MRI scans from 16 female fetuses (23-37 weeks gestation).
Suspicious US findings preceded MRI diagnosis of ovarian cysts.
Multiplanar MRI protocol used for cyst characterization; comparison with US and postnatal data.

Main Results:

Simple cysts in 10/16 fetuses, complex cysts in 7/16.
MRI confirmed US diagnosis in 11/16 cases (69%).
MRI provided additional diagnostic information in 5/16 cases (31%).
Postnatal US showed spontaneous resolution or size decrease in 6/16 cases.
Prenatal diagnoses confirmed by surgery/histopathology in 4/16 cases.

Conclusions:

Prenatal MRI is effective for visualizing fetal ovarian cysts.
MRI often corroborates US findings but can offer supplementary diagnostic details.
MRI aids in diagnosis, monitoring, and treatment planning for fetal ovarian cysts.
