Electromagnetic breast imaging: results of a pilot study in women with abnormal mammograms. Radiology 2007 May;243(2):350-9. Epub 2007 Mar 30
Study by Poplack SP et al published in Radiology May 2007 used three EM imaging methods: electrical impedance spectroscopy (EIS), microwave imaging spectroscopy (MIS), and near-infrared spectral tomography (NIR).Results from EM breast examinations provide statistical evidence of a mean increase in image contrast of 150%-200% between abnormal (benign and malignant) and normal breast tissue.

Here is the the twelth Radiology Grand Rounds, hosted on the last sunday of each month with archives maintained by me here-
Radiology Grand Rounds
We start this radiology Grand rounds with a Radiology Quiz
It goes like-
Radiology Quiz!
"A young lady in her 30s was referred to me for having serous mixed with blood(haemoserous) discharge from her previous abdominal incision. This discharge increased during her menses and with the same consistency. She had an emergency surgery a year ago for a ruptured uterus from pyometra (pus within the uterus) She was found to have a congenital (from birth) anomaly. This is her hysterogram"
Blast from the Past
Here is an interesting write up about the X-ray discovery
""Is it light?""No.""Is it electricity?""Not in any known form.""What is it?""I don't know."And the discoverer of the X rays thus stated as calmly his ignorance of their essence as has everybody else who has written on the phenomena thus far."
Radiology Journal Section
Choosing and using bibliographic software
"I’m sure most of you out there have a collection of articles gathered from many journals, and neatly (or not) filed away in your office. Reading and indexing information from the literature used to mean trips to the library with the photocopy card and sitting down with the highlighter to read them.Starting in the late 90’s, many journals started posting abstracts and full text articles online. Pubmed also became a huge resource for searching the most recent literature for citations. All of these electronic references need to be stored somewhere, and paperless filing is becoming a much more viable option. Hard drives have almost limitless memory, and interfaces for saving references electronically have become much more user friendly. Now you need to decide how to choose bibliographic software, and how you will use it."
Alvaro Fernandez presents Lifelong Learning and New Neurons in Adults posted at Brain Fitness. We will need new imaging methods to see this in action-not even fMRI allows us to see neurogenesis take place.

Siemens proves feasibility of MR/PET hybrid
"The first brain images produced simultaneously with a prototype MR/PET scanner were shown at the Siemens Medical Solutions booth and in a scientific session in Berlin. The device, currently in development at a Siemens lab, integrates a PET detector into the bore of a 3T scanner. "

NEJM features a case of azygos lobe with fissure along with metastatic nodule from osteogenic sarcoma, check out images and case details here-
NEJM-Azygos lobe
What is azygos lobe?
"Abnormal fissures and lobes of the lungs are common and usually insignificant. A lobe of the azygos vein appears in the right lung in about 1 percent of people. It develops when the apical bronchus grows superiorly medial to the arch of the azygos vein instead of lateral to it. As a result, the azygos vein comes to lie at the bottom of a deep fissure in the superior lobe of the right lung."

On popular demand here is the Radiology quiz. What is the diagnosis? this is a T2 weighted axial MRI image. Kindly submit your answers in the comments section. Correct answer will be put up here within this week.
DIAGNOSIS-
Diastematomyelia
Discussion: The congenital entity of diastematomyelia results from a splitting of the notochord during early development; the etiology of this phenomenon is, at present, uncertain. The result is a complete, longitudinal division of the spinal cord over a variable distance. The abnormality is most frequently encountered in the upper lumbar region, but may occur anywhere else along the length of the spinal cord. Division of the cord is often asymmetrical (i.e.), parasagittal); however, each hemicord possesses it's corresponding anterior and posterior horn cells and ipselateral nerve roots. Two subdivisions are recognized, and are described as follows:
Type I (50%): split cord, surrounded by a normal undivided arachnoid-dural sleeve; no septum (diastem)
Type II (50%): split cord; however, each hemicord is invested by a separate dural sleeve, divided by a fibrous, cartilaginous or bony septum (diastem).
Associated clinical/radiographic findings:
Vertebral anomalies associated with defective neural tubeclosure, resulting in the gamut of spinal dysraphisms.
Tethered cord, thickend filum terminale )75%)
Meningomyelocele
Intra/extradural lipoma
Dermal sinus
