1) As an intern, GP or a gen med resident, you are constantly exposed to MR imaging of the brain. This is a complicated imaging modality that requires a radiologist for optimum analysis and reporting. But you must know the basic sequences and how to identify them.
2) The five most common sequence that we use in internal medicine are the T1 (with or without contrast), T2, FLAIR, DWI and ADC sequences. SWI/GRE sequences are also used in certain cases.
3) First check whether the soft tissue of the scalp and the skull (black) are visible or not --> if yes, you are dealing with T1,T2 or FLAIR.

Pterygopalatine fossa🧵- inspired by ?s from med students in neuroanatomy lab & a resident w/ case of perineural tumor spread on same day! #meded #FOAMrad #medtwitter #medstudents #radiology #neurorad #HNrad #radres #neurology #ENT #temporalbone #neurosurgery #neuroanatomy

The PTERYGOPALATINE FOSSA (PPF) is a space deep in the face/skull base, bordered anteriorly by the maxilla (max sinus), posteriorly by the pterygoid base of the sphenoid, and medially by the perpendicular plate of the palatine bone. 2/22
It’s best to think of the PPF as a crossroads/intersection. Think about the roads that lead to and from it, and the cast of characters that pass through.

Some like to simplify/visualize the PPF as a cube or inverted pyramid.

Everyone loves those pretty colored fMRI pictures with the blobs. But what do they mean? How do they make them?
A #tweetorial called “F— that: Understanding fMRI”. #FOAMed #medtwitter #Medstudenttwitter #neurotwitter #FOAMrad #neuroradiology #radiology
2/
fMRI is based on a principle called “neurovascular coupling.” This is the principle if there is increased neuronal activity in a region, there will be increased blood flow to that region to meet the increased demand
3/
Think of it like a baby crying because it is hungry—parents immediately rush to feed it. The increased oxygen demand of the neurons immediately brings increased fuel to feed it.

These frontal & lateral views belong to a patient with a history of lung cancer which presented with a newly developed dyspnea. Considering the patient’s history and CXR findings,what is the most likely cause of the elevation of the right hemidiaphragm?
#chestrad #radiology Image
Hint👉 I wanted to discuss about this subject and I incidentally encountered this case! Honestly speaking it's not complicated case ,but the question is worthy of noticing!
So do you think atelectasis of the R.U lobe is the main culprit?The answer based on many references is Not!
🛑Answer part 1
Phrenic nerve paralysis is a common cause of elevation of one side of the diaphragm.
👉Take home message:
The combination of a lung or mediastinal mass and elevation of the diaphragm strongly suggests phrenic nerve paralysis.
Eventration is a different entity!

I'll be adding short important points which would hopefully help in remembering certain concepts during #PLAB preparation, to this thread🧵every now and then as I take them out from my scattered notes. Feel free to comment your tips and tricks which would help others, as well 👇
Please don't take any of these as medical advice 😂🙏. Real life stuff is much more nuanced. These are just clinchers for the sake of the exam.

1/5 In looking at the #frontline #digitisation #RFI for EPR suppliers I note that there isn’t any mention of requirements to populate #sharedcarerecords or support #interoperability standards such as #ukcore. After 20+ years, why doesn’t the NHS centre get this? A short 🧵
2/5 Interoperability is at least as important as the functional list of requirements. Regions (not Trusts and even not ICSs) are standardising on capability, not systems - e.g Maternity, #epma, specialist systems like ophthalmology. EPRs must be able to work with other systems
3/5 Also, how should an #EPR work within a #pathology and a #radiology network not co-terminus with an ICS? These are more organic and high data liquidity through interoperability is key. That’s another interoperability dimension we should be including.

An in-depth review of Tibial Pilon Fractures.

If you’re interested in orthopedics, you’ll definitely want to check this review out.

🦴⚒️🧵👇

To view our past reviews, visit:
💻 myorthoreviews.com📱 Image
Most tibial pilon fractures result from high-energy axial loading through the talus.

They are also commonly referred to as Tibial Plafond fractures. The tibial plafond is the distal articular surface of the tibia, which gained the name from its French meaning, "ceiling". Image
The term tibial pilon was first used by Étienne Destot in 1911 to describe the interaction of the distal tibia and talus during axial loading.

Pilon is the French term for "pestle".

The term was later adopted as a term for vertical impaction fractures of the distal tibia. Image

The DISCHARGE trial in online on the NEJM and it confirms what we all experience every day using CCT in a proper manner. CCT is safer, reliable and allows better management of stable patients with suspected obstructive CAD as compared to invasive strategy.
The main observation that comes to my mind however is still the very low prevalence of patients with obstructive CAD (25%) in both arms (CT and ICA). This is well known from previous studies and it is related to the selection criteria adopted for referral, partly.
The fact that still we send for an invasive and costly examination (CAG/ICA) this huge number of patients is simply astonishing in 2022. Healthcare cannot be managed like this, especially in universal systems like Italy, Germany, UK, Canada,...

An in-depth review of Humeral Shaft Fractures.

If you’re interested in orthopedics, you’ll definitely want to check this review out!

🦴⚒️🧵👇

To view our past reviews, check out:
💻 myorthoreviews.com📱 Image
The humeral shaft is defined as the area distal to the surgical neck and proximal to the epicondyles.

The commonality of fracture is:
Middle ⅓ > Proximal ⅓ > Distal ⅓ shaft

The deforming forces of humeral shaft fractures usually result in what type of deformity?
Due to the muscular pull of the deltoid on the proximal fragment and medial/superior pull on the distal fragment, humeral shaft fractures tend to develop varus angulation.

Humeral shaft fractures are forgiving, and modest angulation can be overcome by the shoulders' large ROM. Image

The ACL is the primary restraint to anterior tibial translation and also plays a role in rotary stability

It is composed of two bundles, named based on their tibial insertions:
✯ Anteromedial
✯ Posterolateral

What structure separates the femoral insertions of the two bundles?
AM bundle:
✯ Tightest in Flexion
✯ Resists anterior tibial translation
✯ Tested by Lachman's/Anterior Drawer

PL bundle:
✯ Tightest in Extension
✯ Rotatory Restraint
✯ Tested by Pivot Shift

The bifurcate ridge separates the femoral insertions of the AM and PL bundles.

🦴⚒️🧵👇

To view our past reviews visit: myorthoreviews.com
Proximal humerus fractures are common, accounting for around 5% of all fractures with increasing frequency with age.

They are most common in elderly females and are considered a fragility fracture.

Which nerve is most commonly injured in proximal humerus fractures?
The axillary nerve passes medial to the surgical neck and is most commonly injured in proximal humerus fractures.

Sensation testing over the lateral shoulder may be performed as deltoid testing may be difficult.

Which artery provides the main blood supply to the humeral head?

An in-depth review of Clavicle Fractures.

If you're interested in orthopedics you won't want to miss this one!

🦴⚒️🧵👇
Clavicle fractures are typically the result of a fall onto the shoulder and are one of the most common fractures in children.

They may also occur from direct trauma, seizures, or a fall onto an outstretched hand (FOOSH).
The clavicle serves as the connection between the UE and axial skeleton.

It is the first bone to ossify and the last to fuse. It is S-shaped and widest medially.

Most fractures occur in the middle 1/3rd, roughly 80%, which is the thinnest segment.

An in-depth review of intertrochanteric and subtrochanteric hip fractures.

If you're interested in orthopedics you won't want to miss this one!

🦴⚒️🧵👇
Basicervical femoral neck, intertrochanteric (IT), and subtrochanteric (ST) hip fractures are different from femoral neck fractures in that they are extracapsular.

Extracapsular fractures, unlike intracapsular femoral neck fx, have a low likelihood of blood supply disruption/AVN
Anatomy:
The calcar femorale is an extension of cortical bone from the proximal shaft to the posteromedial femoral neck. It aids in weight distribution from the hip to the proximal femoral shaft.

The subtrochanteric region extends 5 cm below the lesser trochanter.

An in-depth review of Ankle Fractures.

If you're interested in orthopedics you'll definitely want to check this review out!

🦴⚒️🧵👇
The ankle is a complex hinge joint comprised of the tibial plafond, talar dome, and distal fibula.

Ankle fractures most commonly occur in elderly females, with roughly 70% being isolated malleolar, 20% being bimalleolar, and 5-10% being trimalleolar. (1)
When first examining a patient with an ankle injury, you can utilize the Ottawa Ankle Rules to determine if you should x-ray the patient.

An in-depth review of pediatric femoral shaft fractures.

If you're interested in orthopedics or pediatrics you'll definitely want to check this review out!

1/10
Pediatric femoral shaft (PFS) fractures constitute a small portion of pediatric fractures roughly 1-2% with a bimodal age distribution

Most common causes:
✯ Toddlers: falls
✯ Teenage/adolescent: MVA
In children younger than walking age child abuse must be suspected. As high as 80% of PFS fractures in this age group are due to child abuse.

In the toddler age group as high as 25% of PFS fractures are due to child abuse, so it must be ruled out.

Beau’s lines (transverse ridge) and onychomadesis (nail shedding) common in kids! Often seen in a post-viral setting.

Common culprit = hand foot mouth disease!

Congenital malalignment of the great toenails – lateral deviation of the first toenails. More common than you think. Start looking at more toes and you’ll see it! Can improve with time or persist. Risk for nail thickening or ingrown nails.
