2/In perfusion imaging, we want to know how blood is flowing
Usually, we do that by adding IV contrast to blood—to go along for the ride. We can track contrast by changes in MR signal
So if contrast runs w/blood, we can track blood by extension & know how it’s flowing. #RGPhx

3/But what if we want to do perfusion imaging & don’t want to use contrast?
For example, in kids, we’d prefer not to give contrast.
Also, if there is an allergy, we REALLY don’t want to give contrast.
There must be another way.

Understanding venous anatomy is critical to performing a complete and accurate exam. Deep venous anatomy is less variable than superficial venous anatomy.
#RGphx
#RGphx
Superficial venous anatomy is more variable. Understanding the anatomy, drainage into the deep venous system, and common anatomic variants, are important.

Cholecystectomy is one of the most performed surgeries. Radiologists and surgeons will, therefore, inevitably encounter several post-cholecystectomy complications. This article reviews role of imaging in diagnosing, preventing, and managing surgical complications.

Three major consensus papers were published between 2019 and 2020: the SRU Consensus Update on Adnexal Cysts, the O-RADS US Consensus Guideline, and the Management for Incidental Adnexal Findings on CT and MRI (ACR White Paper).
#RGphx 2/9
#RGphx 2/9
Most simple adnexal cysts do not require follow-up. The updated SRU guidelines provide thresholds for follow-up of 3-5 cm for postmenopausal and 5-7 cm for premenopausal patients. If a cyst decreases in size on follow-up, continued imaging is usually unnecessary.

CNS β-amyloid deposits ➡️cerebral amyloid angiopathy (CAA) & Alzheimer disease (AD).
CAA is an important cause of multiple intracerebral hemorrhages or cerebral microbleeds, or alternatively, a single hemorrhage in the presence of cortical superficial siderosis.

The 2019 Bosniak classification is very helpful to better characterize cystic renal masses. But there are significant changes compared to the prior edition. This pictorial by some of the brightest minds in RCC is exactly what we need to clarify some of the new changes. #RGphx
Just to understand the reasoning for some of the changes in the Classification, let's start with a quiz; What is the estimated 10-year risk of death from a T1a (<4 cm, limited to the kidney) cystic RCC?
#RGphx @cookyscan1 @RadG_Editor
#RGphx @cookyscan1 @RadG_Editor
Given the low mortality from cystic renal masses, a greater emphasis has been put on specificity rather than sensitivity in the new edition -> a greater number of cystic renal masses are placed into lower Bosniak classes to reduce unnecessary imaging or treatment.

Before 9 months of age, only the metopic suture can be fused normally. Sagittal, coronal & lamboid sutures narrow during childhood but should not fuse. CT is imaging modality of choice- describe shape/synostosis, ICP & vascular anatomy

In non-syndromic patients, usually 1 suture is involved: sagittal > coronal > metopic > lamboid.

Pancreatic injuries are frequently overlooked on initial CT due to the low frequency of these injuries, associated nonspecific clinical features, and relatively subtle imaging findings, and the presence of associated multiple organ injuries.

DECT enables the synthesis of a wide array of images from a single acquisition because of the availability of CT projection data at more than one polychromatic energy level. Currently, six major approaches are used for DECT.
