I just completed (a rather long) Day 4 at Aga Khan Hospital, here in Dar es Salaam, Tanzania (in case you didn’t know where I was). As usual, time flies when you’re having fun, and I really am enjoying my time here.
Soft-tissue attenuation can be a problem in cardiac Nuclear Medicine. Now, I’m somewhat removed from this as the Cardiologists
have stolen/taken over now read the MIBI perfusion scans. My newly minted Chief Tech back home reminded me before I came here that prone scanning would help here, and I suggested we try this with today’s solitary MIBI patient. (There was a second, but he had to meet with government officials, and apparently my letter did not get him out of whatever it was he had to do.)
The Siemens eSoft interface is not incredibly intuitive for setting scan protocols (but the hardware is bullet-proof, so I give them a pass), and we had to resort to hand-drawn schematics to confirm to ourselves that when prone, the patient should be scanned from LPO to RAO, and that a 90-degree orbit of the two heads opposed at 90 degrees would yield 180 degrees of coverage. The things I do for my patients…
The rest of the day was consumed with monitors and their connections to Ultrasound scanners. While the Radiology Department is about to go completely digital with Agfa PACS (don’t say anything), moving off the venerable Clear Canvas (which actually works quite well here), the U/S scanners do NOT have DICOM licenses. This is a sad situation I faced in Ghana. It seems that over here, the vendors charge EXTRA for DICOM. Not nice, folks. Not nice at all. So the three U/S machines here aren’t connected to anything except printers. Now supposedly there will be funds allocated to get the DICOM running once full PACS is here, but in the meantime, there is the desire to view the images in real-time. Which means looking at the monitor. Originally, the thought was to purchase a large monitor and a KVM switch to multiplex the inputs from the three scanners into one station. But by the time I got here, the idea had gelled a bit and the Chairman realized that three small monitors cost less than one big one and a multiport, multi connection KVM. So I spent a good bit of time with one of the guys from IT, connecting a monitor to the various scanners. One scanner, fortunately in the room right next to the reading room, has only a DVI output. The other two have VGA. So it now becomes a matter of figuring out how to string cables to connect the various rooms. That one is above my pay-grade at the moment.
We did discover whilst trying various DVI cables in various sockets that there are two main (actually more) versions of DVI, DVI-I and DVI-D. (And DVI-A, but that’s beyond our scope)…
DVI-I has extra pins not found with DVI-D, and so a male DVI-I plug won’t fit in a female DVI-D socket. Sounds like some dysfunction to me after the morning lecture. But the good news is that we now know what cables we need, and the only remaining question is how to run them.
With that solved, I shall have some dinner, finish my packing for my quick trip to Ngorongoro Crater tomorrow, and turn in early to be ready for my early morning talk.
