Armed police swooped on the hospital just before 11am yesterday after the blast in a car park.
Dramatic pictures showed the car on fire just inches from the main entrance to the hospital, where 30 babies are born each day.
Police confirmed today the horror is being treated as a terror incident.
Three suspects - aged 29, 26 & 21 - were arrested yesterday under the Terrorism Act.
It was confirmed a fourth man, 20, was held today by officers with all four suspects to be quizzed by counter-terrorism officers this afternoon.
Assistant Chief Constable Russ Jackson, Counter Terrorism North West, said the bomber was picked up in Rutland Avenue just before 11am.
He then asked to be taken to Liverpool Women's Hospital, which is around ten minutes away.
As the taxi approached the hospital, the explosion tore through the car and engulfed it in a fireball - killing him and injuring cabbie Dave Perry.
Police believe they know his identify but no details have been released.
Officers are still trying to establish a motive for the terror blast and said the investigation is "continuing at pace".
TERROR PROBE
ACC Jackson said they “cannot at this time draw any connection” with Remembrance Sunday events nearby but confirmed it is a line of inquiry.
The officer added: "Remarkably, the taxi driver, escaped from the cab. He has been treated for the injuries he sustained and has now been released from hospital.
"Emergency services quickly attended the scene and Merseyside Fire and Rescue put out the fire following which it quickly became apparent that the passenger remained in the vehicle and was deceased.
"It is not clear what the motivation for this incident is.
"Our enquiries indicate that an improvised explosive device has been manufactured and our assumption so far is that this was built by the passenger in the taxi.
"The reason why he then took it to the Women's Hospital is unknown, as is the reason for its sudden explosion.
"Although, the motivation for this incident is yet to be understood, given all the circumstances, it has been declared a terrorist incident and Counter Terrorism Policing are continuing with the investigation."
'REMAIN VIGILANT'
The officer confirmed two addresses in the city have been searched as a result of the investigation.
Three of the suspects were arrested yesterday at Sutcliffe Street in the Kensington area of Liverpool, while today's arrest was made in the same area.
Cops have found "significant items" at a home searched in Rutland Avenue with eight families living nearby evacuated.
Merseyside Chief Constable Serena Kennedy said: "There is no specific threat to the area, but I have asked for patrols to be increased right across Merseyside."
She also urged people to "remain calm" but "vigilant and alert".
