Radiology boards wisdom of the day:
PhysicsThe ability to see a large low contrast object depends upon the contrast-to-noise ratio of the imaging system. Increasing CT slice thickness increases the number of photons used per voxel, thus decreasing the noise and increasing the contrast-to-noise ratio.

Radiology on-call cases:
Parenchymal hemorrhage and subdural hematoma - acute This axial noncontrast head CT demonstrates an acute subdural hematoma overlying the left frontal lobe (black full arrows). The hematoma is subdural because it is contained by the falx cerebri and does not cross to the contralateral side (dotted black arrow). Also noticed is acute blood with associated edema in the left frontal brain parenchyma (white arrow).

A new program was launched on Radiolopolis: "Dare To Share!". Dare To Share! is a project, which allows sharing cases between researchers and colleagues. Users may find interesting or needed cases/images for different kind of projects (studies, books, publications, presentations etc.) while assuring the owner's credentials/copyright of the case. Direct contact between the searcher and the owner of the case provides also a good opportunity to get to know new, potential partners for future projects. More infos about the Dare To Share! program can be found here.

| Magnetic Resonance Imaging of the Fetal Central Nervous System, Head, Neck, and Chest |
|
This article will briefly review safety and practical aspects of fetal MRI. We will then provide a concise summary of the most common indications for fetal MRI, and discuss the differential diagnosis and role of MRI in assessment of fetal brain, head, neck, spine, and chest anomalies.

| A Radiologic Review of Common Breast Disorders in Pregnancy and the Perinatal Period |
|
The imaging changes in the breast associated with pregnancy and the perinatal period may not only deviate from the baseline appearance for each patient, but may also mimic disease or confound evaluation of disease. The hormonal changes can influence a range of disorders, from benign or inflammatory changes to malignant tumors. Moreover, outcomes differ from those of similar pathologies in nonpregnant patients, owing to either physiological changes or delays in diagnosis and treatment. Ultrasonography is the preferred imaging modality for evaluation during pregnancy and lactation, as its sensitivity for carcinoma is nearly 100% (Sabate JM, Clotet M, Torrubia S, et al, 2007; Radiographics 27 suppl 1:S101-S124). Therefore, an understanding of the specific pregnancy-associated pathologies and ...

| Imaging of Trauma in a Pregnant Patient |
|
Trauma is the number one nonobstetric cause of maternal death. This chapter presents the latest consensus from the literature on the best approach to radiographic imaging of these patients. The central issues of discussion include the rationale and protocols for screening for pregnancy in trauma setting; the effects of radiation and its risks to the fetus; obtaining informed consent; how to estimate fetal dose; and the role of ultrasound, computed tomography, and magnetic resonance imaging, including the intravenous contrast agents used for the assessment of abdominal trauma. The team approach to the management of these patients is also highlighted.

| Imaging of the Placenta with Pathologic Correlation |
|
The placenta functions to nourish and protect the fetus. Imaging of the placenta can have a profound impact on patient management, owing to the morbidity and mortality associated with various placental conditions. To fully appreciate placental pathology, its physiology, anatomy, and variant anatomy will be outlined. Placental conditions affecting the mother and fetus include molar pregnancies, placental hematoma, abruption, previa, accreta, vasa previa, choriocarcinoma, and retained products of conception. Ultrasonography remains the definitive modality in diagnosing most of these conditions, with magnetic resonance imaging remaining an adjunctive measure. Computed tomography is occasionally used in cases of trauma and tumor staging.

| Letter From the Guest Editors: Multimodality Imaging of the Pregnant Patient |
|
It is well recognized that radiation exposure during pregnancy carries significant risk to the fetus. Many factors must be taken into consideration when faced with a pregnant patient who requires medical imaging. The risk/benefit ratio to the mother must always outweigh the risk of radiation exposure to the fetus. Once the benefit of imaging has been determined to outweigh fetal risk, careful thought must be given to the appropriate imaging modality to be used, as well as to the mandatory employment of radiation dose reduction techniques.

| Adnexal Masses in Pregnancy |
|
Adnexal masses are often seen in the gravid patient. With current advances in technology, an increased number of adnexal masses are incidentally discovered on antenatal screening ultrasonography examinations. Sonography is the first-line imaging modality for any adnexal mass. However, further evaluation with magnetic resonance imaging (MRI) may be critical for diagnosis. For example, MRI can determine whether a mass contains fat, which can be useful in the diagnosis of a teratoma. Characteristic features of nonneoplastic and neoplastic ovarian lesions seen on sonography and MRI will be discussed. Radiologic features that help distinguish benign from malignant neoplasms will be described. Additional lesions specific to the gravid state must be considered in the differential diagnosis when a...

| Nontraumatic Abdominal Pain in Pregnancy: Imaging Considerations for a Multiorgan System Problem |
|
Nontraumatic abdominal pain in the pregnant patient can present a clinician with a variety of diagnostic possibilities. The overlap between signs and symptoms expected in normal pregnancy and these many pathologic possibilities does little to help focus the clinician's diagnostic efforts. Fear of ionizing radiation's effects on the fetus has driven efforts to refine medical imaging algorithms in such a way as to attempt to eliminate its use at all cost. In today's world, we are nearly there. In this review the differential diagnosis of nontraumatic abdominal pain in the pregnant patient will be explored. Of note is the recurring theme that much of what can be done today with regard to diagnostic imaging, both in general and with regard to this specific subset of patients, centers on the us...

| Pregnancy-Induced Acute Neurologic Emergencies and Neurologic Conditions Encountered in Pregnancy |
|
Neurologic complications and conditions associated with pregnancy are rare. Frequently, presenting symptoms of neurologic conditions are nonspecific and can overlap with normal symptoms of pregnancy. As a result, clinical assessment can be insufficient to differentiate symptoms of a normal pregnancy from a neurologic disorder. It is imperative that the radiologist have a basic familiarity with the most common neurologic conditions encountered in pregnancy. The most commonly imaged acute and nonemergent disorders will be described, including eclampsia, cerebrovascular disease including cerebral venous thrombosis, postpartum cerebral angiopathy, multiple sclerosis, tumors, Bell palsy, Guillain-Barré syndrome, and pituitary disorders.

| Fetal Risk in Diagnostic Radiology |
|
It is not uncommon to encounter situations in which radiologic examinations are necessary for accurate diagnosis and effective treatment of an expectant mother. The potential deleterious health consequences to the developing embryo and fetus from in utero irradiation include fetal death, congenital malformations, growth retardation, and carcinogenic and mutagenic effects. The likelihood of each effect is greatly dependent on the radiation dose and the gestational age of the conceptus at the time of exposure. In general, the average fetal doses from diagnostic imaging are

| Pulmonary Embolism Evaluation in the Pregnant Patient: A Review of Current Imaging Approaches |
|
Pregnancy is characterized by a higher incidence of pulmonary embolism (PE) than in age-matched nonpregnant women. However, the diagnosis of PE during pregnancy might prove to be more difficult than in the general population. Clinicians strongly rely on imaging studies to establish a prompt diagnosis. On reviewing this article, the reader will learn the pros and cons of the 2 main imaging studies used in the evaluation for PE, computed tomography of the pulmonary arteries and lung scintigraphy. Radiation dose and other important factors to consider during the evaluation for PE in pregnancy are highlighted so that clinicians and radiologists can choose the most appropriate imaging study for diagnosis.
