Visual search in breast imaging: A review.
Abstract Breast cancer is the most common cancer among females worldwide and large volumes of breast images are produced and interpreted annually. As long as radiologists interpret these images, the diagnostic accuracy will be limited by human factors and both false-positive and false-negative errors might occur. By understanding visual search in breast images, we may be able to identify causes of diagnostic errors, find ways to reduce them, and also provide a better education to radiology residents. Many visual search studies in breast radiology have been devoted to mammography. These studies showed that 70% of m...

GoogleFOAM
The expansion of the FOAM world is a bit like blowing up a balloon. The early stages involved a lot of effort for a small increase in size, but as it gets bigger, the resistance is falling away and expansion is getting faster and faster. Obviously this is a good thing. But it can make it easier for us all to get lost and there is the danger of information overload — indeed, I’ve written a guide to (in)sanity in the age of FOAM that I continually update, the LITFL post on Information Overload. The FOAM world is now impossible to keep up with. We need to be able to find what we want when we need it, according to our ...

Ultrasound for diagnosis of birth weight discordance in twin pregnancies
CONCLUSIONS: Very low-certainty evidence suggests that EFWD identified by ultrasound has low sensitivity but good specificity in detecting BWD in twin pregnancies. There is uncertain diagnostic value of EFWD; this review suggests there is insufficient evidence to support this index as the sole measure for clinical decision making to evaluate the prognosis of twins with growth discordance. The diagnostic accuracy of other measures including amniotic fluid index and umbilical artery Doppler resistive indices in combination with ultrasound for clinical intervention requires evaluation. Future well-designed studies could also ...

Stress echocardiography for the diagnosis of coronary artery disease: an evidence-based analysis.
The objective of the analysis is to determine the diagnostic accuracy of stress echocardiography (ECHO) in the diagnosis of patients with suspected coronary artery disease (CAD) compared to coronary angiography (CA). STRESS ECHOCARDIOGRAPHY: Stress ECHO is a non-invasive technology that images the heart using ultrasound. It is one of the most commonly employed imaging techniques for investigating a variety of cardiac abnormalities in both community and hospital settings. A complete ECHO exam includes M-mode, 2-dimensional (2-D) images and Doppler imaging. In order to diagnosis CAD and assess whether myocardial ischemia is ...

Where ’s Waldo? The utility of a complicated visual search paradigm for transcranial Doppler-based assessments of neurovascular coupling
Conclusions We recommend complicated visual search paradigms such as Where’s Waldo be considered for future transcranial Doppler-based neurovascular coupling studies.

Derivation and validation of text search algorithms for renal and adrenal lesion identification in radiology text reports.
CONCLUSIONS: Textual radiology reports can be analyzed using common statistical software to accurately determine the probability that important abnormalities of the kidneys or adrenal glands exist. These methods can be used for case identification or epidemiological studies. PMID: 31977309 [PubMed - as supplied by publisher]

Nuchal translucency and major congenital heart defects in fetuses with normal karyotype: a meta-analysis.
CONCLUSION: Approximately 44% of CHDs in chromosomally normal fetuses have NT>95(th) centile and 20% have NT>99(th) centile. However, there is increased heterogeneity across studies, which largely remains even in subgroup analyses of studies of apparently similar design, potentially indicating the presence of some residual unidentified bias.

Inflammation: an important parameter in the search of prostate cancer biomarkers
Conclusions: The present study indicates that inflammation might be a confounding parameter during the proteomic research of candidate biomarkers of PCa. These results indicate that some possible biomarker-candidate proteins are strongly influenced by the presence of inflammation, hence only a well-selected protein pattern should be considered for potential marker of PCa.

Induction of ovulation with buserelin in jennies: In search of the minimum effective dose.
Abstract The aim of this study was to evaluate the minimum dose of buserelin acetate (buserelin) able to induce ovulation between 24 and 48h from treatment (positive response) in estrous jennies. Jennies were studied during a total of 172 estrous cycles: ovarian activity was routinely monitored by ultrasound; when the dominant follicle reached a diameter of 33±1mm, estrous jennies were treated by subcutaneous administration of different doses of buserelin, 3.3mg (N=11), 1.5mg (N=21), 0.8mg (N=12), 0.4mg (N=16), 0.2mg (N=13), 0.1mg (N=16), 0.04mg (N=14), 0.02mg (N=16), or employed as controls (N=53). Single jennie...

Beckwith-Wiedemann syndrome: What do you search in prenatal diagnosis? About 14 cases.
CONCLUSION: This study identified some prenatal ultrasound signs that should alert the clinician to the possibility of BWS. A genetic conseling, after confirmation by molecular diagnosis, could be proposed in a near future in prenatal, and could improve postnatal management strategies for these affected children at high postnatal risk.

The Role of Ultrasound in Diagnosis of the Causes of Low Back Pain: a Review of the Literature
Conclusions: While the first researches on employing ultrasound in diagnosis of patients with LBP had been focused on spinal canal diameter, recent studies have been mostly performed to evaluate the role of transabdominal and paraspinal muscles on core stability and thereby LBP occurrence. On the other side, Doppler ultrasonography has recently played an important role in objective measurement of joint laxity as a common etiology for LBP. Doppler imaging also in pregnant patients with LBP has been recommended as a safe and sensitive method. As conclusion, according to recent and most prestigious studies, focusing more on t...
