Discrimination between Glioblastoma and Solitary Brain Metastasis: Comparison of Inflow-Based Vascular-Space-Occupancy and Dynamic Susceptibility Contrast MR Imaging [FUNCTIONAL]

BACKGROUND AND PURPOSE:

Accurate differentiation between glioblastoma and solitary brain metastasis is of vital importance clinically. This study aimed to investigate the potential value of the inflow-based vascular-space-occupancy MR imaging technique, which has no need for an exogenous contrast agent, in differentiating glioblastoma and solitary brain metastasis and to compare it with DSC MR imaging.

MATERIALS AND METHODS:

Twenty patients with glioblastoma and 22 patients with solitary brain metastasis underwent inflow-based vascular-space-occupancy and DSC MR imaging with a 3T clinical scanner. Two neuroradiologists independently measured the maximum inflow-based vascular-space-occupancy–derived arteriolar CBV and DSC-derived CBV values in intratumoral regions and peritumoral T2-hyperintense regions, which were normalized to the contralateral white matter (relative arteriolar CBV and relative CBV, inflow-based vascular-space-occupancy relative arteriolar CBV, and DSC-relative CBV). The intraclass correlation coefficient, Student t test, or Mann-Whitney U test and receiver operating characteristic analysis were performed.

RESULTS:

All parameters of both regions had good or excellent interobserver reliability (0.74~0.89). In peritumoral T2-hyperintese regions, DSC-relative CBV (P < .001), inflow-based vascular-space-occupancy arteriolar CBV (P = .001), and relative arteriolar CBV (P = .005) were significantly higher in glioblastoma than in solitary brain metastasis, with areas under the curve of 0.94, 0.83, and 0.72 for discrimination, respectively. In the intratumoral region, both inflow-based vascular-space-occupancy arteriolar CBV and relative arteriolar CBV were significantly higher in glioblastoma than in solitary brain metastasis (both P < .001), with areas under the curve of 0.91 and 0.90, respectively. Intratumoral DSC-relative CBV showed no significant difference (P = .616) between the 2 groups.

CONCLUSIONS:

Inflow-based vascular-space-occupancy has the potential to discriminate glioblastoma from solitary brain metastasis, especially in the intratumoral region.

Alison Roman Bashed Marie Kondo and Chrissy Teigen, and It Did Not Spark Joy

Alison Roman’s latest comments about Marie Kondo have not sparked joy.

In an interview with The New Consumer about her increased popularity and the avenues she might pursue to capitalize on it, the popular food columnist discussed her hesitance to put her name on a product line—citing the Japanese organization maven and Chrissy Teigen as examples of what she did not foresee in her own future.

“I have a collaboration coming out with [the cookware startup] Material, a capsule collection,” Roman said. “It’s limited edition, a few tools that I designed that are based on tools that I use that aren’t in production anywhere—vintage spoons and very specific things that are one-offs that I found at antique markets that they have made for me.”

The Queen’s Coronavirus Message to Britain: ‘Never Give Up, Never Despair’

via YouTube

The Queen gave a 75th anniversary VE Day speech Friday night that doubled as a rallying cry against coronavirus. “Never give up, never despair, that was the message of VE Day,” she told the British people.

Second World War heroes would “recognize and admire,” the sacrifices the British were making today in the fight against coronavirus, the Queen added. It was her second major coronavirus-themed speech to the nation.

“It may seem hard that we cannot mark this special anniversary as we would wish. Instead we remember from our homes and our doorsteps. But our streets are not empty,” the Queen said, “They are filled with the love and the care that we have for each other.”

Burning The Poplar Fluff Blanket Off Park Grass In Spain

This is a video from the Parque del Cidacos in Calahorra, La Rioja, Spain of a controlled burn of the poplar fluff (the very fine, kinda dandelion-like seeds released by female poplar trees) atop the grass in the park. As you can see, the fluff burns incredibly quickly, leaving the grass below unharmed. The time I spelled my girlfriend's name in gasoline in her parent's yard and set it ablaze? Thank God their homeowner's insurance covered detached garages! Keep going for the full video.

Rafe Spall: 'Dieting is the opposite of sex!'

Once the ‘go-to guy for feckless losers’, the actor is now spearheading Apple’s assault on British TV. He talks about flops, racism, chest hair – and Laurence Fox

In October 2005, Rafe Spall was starring in the role he thought he was born to play. Only 21 at the time, he’d bagged a part in Anna Mackmin’s reimagining of Francis Beaumont’s 1607 comedy The Knight of the Burning Pestle at the Barbican. The play isn’t just any old Renaissance play in the Spall household, it’s a hallowed text.

His father (Timothy Spall, you might have heard of him) had played the same part in a 1981 RSC version that changed his life for ever. It was while playing that role he met his wife, Shane, and the pair loved the play so much they decided to give their first child the name of the character his father played: Rafe. To make it seem even more preordained, it was Rafe’s grandmother’s favourite ever performance by his father. No pressure, then.

Selah and the Spades review – teen cliques drama balances satire and surrealism

This uncanny story of preppy drug dealers has a touch of Heathers and a bit of Bret Easton Ellis, and an intriguing take on what high school is really like

Tayarisha Poe, like her partial namesake, has a gift for the uncanny. She is the photographer and film-maker behind this feature debut, which began as an online multimedia project and was developed as a conventional movie through the Sundance screenwriters and directors labs. What has emerged is an intriguing, opaque, tonally elusive story that seems weirdly unfinished. It is set in a privileged high school – a world of ivy-covered stone buildings and shady quadrangles where rich kids are separated into malign and mutually hostile cliques. It has a touch of Donna Tartt and Bret Easton Ellis, a hint of Heathers and a bit of the elegant, disdainful satire of Dear White People.

Somehow, though, it is odder, more stylised and contrived, always holding out the possibility that it is set in the future, or in an alternative present on some other planet, or inside the head of one of its characters who is having a disturbing dream – the kind that ends just as it is about to give up its meaning. Right until the closing credits, I half-expected the face of each person on screen to flip upwards, revealing a Stepford-like set of dials.
